As we continue to study the subject of prayer, the following questions may arise in the minds of many believers: ‘Why should I pray at all if I am only praying for God’s will to be done?  Cannot God do, and will not God do as He purposes to do anyways? Why does He need my prayers to bring about His will and purpose?’ The simplest answer to these questions, would be of course—because God wants us to pray, and we are told to pray. However, beyond that, there are deeper reasons why we need to pray. Although God can, and does do “according to his will in the army of heaven, and among the inhabitants of the earth,” He nevertheless gave to man a certain dominion over this earth, which God has never rescinded. Just as He assigned to the angels certain responsibilities, and bequeaved to them a measure of dominion and control in the spiritual realm, even so He did to man in the natural world. God’s creation is not some huge version of the popular computer program “SimCity”[1], where the player designs his own world, and the images of the people are completely controlled by computerization. God gave men and angels a real part in all that is happening in His creation. He gave them real dominion, real control, and the ability to make real choices and decisions about the realm in which they live. These bequeavements were “without repentance”—which means that God does not take back, nor usurp control over those areas under His creature’s dominion; even if they are not using them for His glory. Lucifer was given certain powers, gifts, and abilities that He still uses in his battle against God. Man was given dominion “over all the earth”; and he still has that dominion in his fallen state—even though he has not brought glory to God by what he has done with the earth.

Dan 4:35 And all the inhabitants of the earth are reputed as nothing: and he doeth according to his will in the army of heaven, and among the inhabitants of the earth: and none can stay his hand, or say unto him, What doest thou?

Gen 1:26 And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.

Psa 8:4 What is man, that thou art mindful of him? and the son of man, that thou visitest him?
5 For thou hast made him a little lower than the angels, and hast crowned him with glory and honour.
6 Thou madest him to have dominion over the works of thy hands; thou hast put all things under his feet:
7 All sheep and oxen, yea, and the beasts of the field;
8 The fowl of the air, and the fish of the sea, and whatsoever passeth through the paths of the seas.

Heb 2:6 But one in a certain place testified, saying, What is man, that thou art mindful of him? or the son of man, that thou visitest him?
7 Thou madest him a little lower than the angels; thou crownedst him with glory and honour, and didst set him over the works of thy hands:
8 Thou hast put all things in subjection under his feet. For in that he put all in subjection under him, he left nothing that is not put under him. But now we see not yet all things put under him.
9 But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.

Rev 7:1 And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree.
2 And I saw another angel ascending from the east, having the seal of the living God: and he cried with a loud voice to the four angels, to whom it was given to hurt the earth and the sea,
3 Saying, Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads.

Rev 18:1 And after these things I saw another angel come down from heaven, having great power; and the earth was lightened with his glory.

Rom 11:29 For the gifts and calling of God are without repentance

1 Sam 15:29 And also the Strength of Israel will not lie nor repent: for he is not a man, that he should repent.

Eze 28:12 Son of man, take up a lamentation upon the king of Tyrus, and say unto him, Thus saith the Lord GOD; Thou sealest up the sum, full of wisdom, and perfect in beauty.
13 Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created.
14 Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire.
15 Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.
16 By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.
17 Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness: I will cast thee to the ground, I will lay thee before kings, that they may behold thee.

Rev 12:7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,

Gen 6:11 The earth also was corrupt before God, and the earth was filled with violence.
12 And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth.

Now, we can already hear the charge by many of how we have contradicted ourselves. We have said previously that God is in complete control of even the minutest details of our lives; and here we say that men and angels have a measure of control over their own sphere of influence. However, both statements are true. God’s power and wisdom are so awesome that He is able to work in, around, and through every action that even evil men and angels may do; in order to bring about His ultimate glory and purpose. In the supreme act of sinful men and demons against God, they crucified Jesus; and in God’s supreme act of love and mercy toward sinful men, He purposed that they do so. Fallen men and angels were all permitted to have their will and way with Christ, and God did not intervene—but why? Because it was already His plan and purpose that His Son die for sinful men upon the tree. Neither were these sinful men and demons driven to do this cruel act by God’s control over them—because had they known God’s purpose, “they would not have crucified the Lord of glory.” Therefore, they had control over what they did, but they were ignorant of, and were not in control of what God was doing.

Acts 4:25 Who by the mouth of thy servant David hast said, Why did the heathen rage, and the people imagine vain things?
26 The kings of the earth stood up, and the rulers were gathered together against the Lord, and against his Christ.
27 For of a truth against thy holy child Jesus, whom thou hast anointed, both Herod, and Pontius Pilate, with the Gentiles, and the people of Israel, were gathered together,
28 For to do whatsoever thy hand and thy counsel determined before to be done.

1 Pet 1:18 Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers;
19 But with the precious blood of Christ, as of a lamb without blemish and without spot:
20 Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,

1 Cor 2:6 Howbeit we speak wisdom among them that are perfect: yet not the wisdom of this world, nor of the princes of this world, that come to nought:
7 But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory:
8 Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.

So then, what of prayer? How does it fit into the eternal purposes of God, and at the same time take into consideration man’s freedom and dominion over the earth? To begin with, when God gave man this dominion, they walked together, and communed together as Father and son. Man was meant to have this union with his Creator, to seek out, and to submit to His perfect wisdom and will in all that he did. God gave to man a great responsibility, and man needed his Creator God to help and to guide him. The reason this world is in such a mess today is that man has tried to run his life and this world without God. As sinners, we came to believe that we didn’t need God; and we don’t want God to interfere with our affairs—unless of course we are dying, or are in some great calamity. However, the purpose of prayer was to be much greater than a call to the heavenly emergency hotline. Prayer was given to man as the means to ask God to intervene for us, to help us, to work on our behalf, and to give us wisdom and understanding. God has always worked through men who have yielded themselves to Him, and who have prayed for God’s will to be done in this earth. To be sure, it is God who came to such men as Abraham, Samuel, and Paul the Apostle, revealed Himself to them, prepared them for His service, revealed to them His will, and gave them a desire to pray for His will to be done. In all of this however, man’s will was never violated, nor was his dominion ever usurped by God.

Eph 3:11 According to the eternal purpose which he purposed in Christ Jesus our Lord:

Psa 2:1 Why do the heathen rage, and the people imagine a vain thing?
2 The kings of the earth set themselves, and the rulers take counsel together, against the LORD, and against his anointed, saying,
3 Let us break their bands asunder, and cast away their cords from us.

Gen 4:26 And to Seth, to him also there was born a son; and he called his name Enos: then began men to call upon the name of the LORD.

Rom 6:13 Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God.

Luke 11:2 And he said unto them, When ye pray, say, Our Father which art in heaven, Hallowed be thy name. Thy kingdom come. Thy will be done, as in heaven, so in earth.

Gen 12:1 Now the LORD had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will shew thee:

1 Sam 3:3 And ere the lamp of God went out in the temple of the LORD, where the ark of God was, and Samuel was laid down to sleep;
4 That the LORD called Samuel: and he answered, Here am I.

Acts 9:1 And Saul, yet breathing out threatenings and slaughter against the disciples of the Lord, went unto the high priest,
2 And desired of him letters to Damascus to the synagogues, that if he found any of this way, whether they were men or women, he might bring them bound unto Jerusalem.
3 And as he journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven:
4 And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me?
5 And he said, Who art thou, Lord? And the Lord said, I am Jesus whom thou persecutest: it is hard for thee to kick against the pricks.
6 And he trembling and astonished said, Lord, what wilt thou have me to do? And the Lord said unto him, Arise, and go into the city, and it shall be told thee what thou must do.

Acts 9:10 And there was a certain disciple at Damascus, named Ananias; and to him said the Lord in a vision, Ananias. And he said, Behold, I am here, Lord.
11 And the Lord said unto him, Arise, and go into the street which is called Straight, and inquire in the house of Judas for one called Saul, of Tarsus: for, behold, he prayeth,
12 And hath seen in a vision a man named Ananias coming in, and putting his hand on him, that he might receive his sight.
13 Then Ananias answered, Lord, I have heard by many of this man, how much evil he hath done to thy saints at Jerusalem:
14 And here he hath authority from the chief priests to bind all that call on thy name.
15 But the Lord said unto him, Go thy way: for he is a chosen vessel unto me, to bear my name before the Gentiles, and kings, and the children of Israel:
16 For I will shew him how great things he must suffer for my name's sake.

Gal 1:15 But when it pleased God, who separated me from my mother's womb, and called me by his grace,
16 To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:

King David was a prime example of how God works through the prayers of men. God had already prepared David’s heart as a young shepherd boy who watched his father’s sheep. In those days God would reveal Himself to David, and would give David a great love for God and faith in God. Later, God Himself would say of David, “I have found David the son of Jesse, a man after mine own heart, which shall fulfil all my will.” God later took David from being a shepherd boy and made him King over all of Israel—under whom that nation reached its zenith of power. God’s greatest work however, was to reveal to David His will in the sending of His Son, the Lord Jesus, through David’s linage. As David had pondered building a Temple for the Ark of God to dwell in, God revealed to him how the Son of David would build the Father’s true house of worship; and that He would reign as “KING OF KINGS, AND LORD OF LORDS” forever and ever. David then began to pray for God’s will to be done, just as He had spoken to him; and God of course, was pleased to answer David’s prayer.

1 Sam 16:1 And the LORD said unto Samuel, How long wilt thou mourn for Saul, seeing I have rejected him from reigning over Israel? fill thine horn with oil, and go, I will send thee to Jesse the Bethlehemite: for I have provided me a king among his sons.
4 And Samuel did that which the LORD spake, and came to Bethlehem. And the elders of the town trembled at his coming, and said, Comest thou peaceably?
5 And he said, Peaceably: I am come to sacrifice unto the LORD: sanctify yourselves, and come with me to the sacrifice. And he sanctified Jesse and his sons, and called them to the sacrifice.
6 And it came to pass, when they were come, that he looked on Eliab, and said, Surely the LORD's anointed is before him.
7 But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart.
10 Again, Jesse made seven of his sons to pass before Samuel. And Samuel said unto Jesse, The LORD hath not chosen these.
11 And Samuel said unto Jesse, Are here all thy children? And he said, There remaineth yet the youngest, and, behold, he keepeth the sheep. And Samuel said unto Jesse, Send and fetch him: for we will not sit down till he come hither.
12 And he sent, and brought him in. Now he was ruddy, and withal of a beautiful countenance, and goodly to look to. And the LORD said, Arise, anoint him: for this is he.
13 Then Samuel took the horn of oil, and anointed him in the midst of his brethren: and the Spirit of the LORD came upon David from that day forward. So Samuel rose up, and went to Ramah.

Acts 13:21 And afterward they desired a king: and God gave unto them Saul the son of Cis, a man of the tribe of Benjamin, by the space of forty years.
22 And when he had removed him, he raised up unto them David to be their king; to whom also he gave testimony, and said, I have found David the son of Jesse, a man after mine own heart, which shall fulfil all my will.
23 Of this man's seed hath God according to his promise raised unto Israel a Saviour, Jesus:

1 Sam 17:34 And David said unto Saul, Thy servant kept his father's sheep, and there came a lion, and a bear, and took a lamb out of the flock:
35 And I went out after him, and smote him, and delivered it out of his mouth: and when he arose against me, I caught him by his beard, and smote him, and slew him.
36 Thy servant slew both the lion and the bear: and this uncircumcised Philistine shall be as one of them, seeing he hath defied the armies of the living God.
37 David said moreover, The LORD that delivered me out of the paw of the lion, and out of the paw of the bear, he will deliver me out of the hand of this Philistine.

2 Sam 7:1 And it came to pass, when the king sat in his house, and the LORD had given him rest round about from all his enemies;
2 That the king said unto Nathan the prophet, See now, I dwell in an house of cedar, but the ark of God dwelleth within curtains.
3 And Nathan said to the king, Go, do all that is in thine heart; for the LORD is with thee.
4 And it came to pass that night, that the word of the LORD came unto Nathan, saying,
5 Go and tell my servant David, Thus saith the LORD, Shalt thou build me an house for me to dwell in?
6 Whereas I have not dwelt in any house since the time that I brought up the children of Israel out of Egypt, even to this day, but have walked in a tent and in a tabernacle.
7 In all the places wherein I have walked with all the children of Israel spake I a word with any of the tribes of Israel, whom I commanded to feed my people Israel, saying, Why build ye not me an house of cedar?
8 Now therefore so shalt thou say unto my servant David, Thus saith the LORD of hosts, I took thee from the sheepcote, from following the sheep, to be ruler over my people, over Israel:
9 And I was with thee whithersoever thou wentest, and have cut off all thine enemies out of thy sight, and have made thee a great name, like unto the name of the great men that are in the earth.
10 Moreover I will appoint a place for my people Israel, and will plant them, that they may dwell in a place of their own, and move no more; neither shall the children of wickedness afflict them any more, as beforetime,
11 And as since the time that I commanded judges to be over my people Israel, and have caused thee to rest from all thine enemies. Also the LORD telleth thee that he will make thee an house.
12 And when thy days be fulfilled, and thou shalt sleep with thy fathers, I will set up thy seed after thee, which shall proceed out of thy bowels, and I will establish his kingdom.
13 He shall build an house for my name, and I will stablish the throne of his kingdom for ever.
14 I will be his father, and he shall be my son. If he commit iniquity, I will chasten him with the rod of men, and with the stripes of the children of men:
15 But my mercy shall not depart away from him, as I took it from Saul, whom I put away before thee.
16 And thine house and thy kingdom shall be established for ever before thee: thy throne shall be established for ever.
17 According to all these words, and according to all this vision, so did Nathan speak unto David.
18 Then went king David in, and sat before the LORD, and he said, Who am I, O Lord GOD? and what is my house, that thou hast brought me hitherto?
19 And this was yet a small thing in thy sight, O Lord GOD; but thou hast spoken also of thy servant's house for a great while to come. And is this the manner of man, O Lord GOD?
20 And what can David say more unto thee? for thou, Lord GOD, knowest thy servant.
21 For thy word's sake, and according to thine own heart, hast thou done all these great things, to make thy servant know them.
22 Wherefore thou art great, O LORD God: for there is none like thee, neither is there any God beside thee, according to all that we have heard with our ears.
23 And what one nation in the earth is like thy people, even like Israel, whom God went to redeem for a people to himself, and to make him a name, and to do for you great things and terrible, for thy land, before thy people, which thou redeemedst to thee from Egypt, from the nations and their gods?
24 For thou hast confirmed to thyself thy people Israel to be a people unto thee for ever: and thou, LORD, art become their God.
25 And now, O LORD God, the word that thou hast spoken concerning thy servant, and concerning his house, establish it for ever, and do as thou hast said.
26 And let thy name be magnified for ever, saying, The LORD of hosts is the God over Israel: and let the house of thy servant David be established before thee.
27 For thou, O LORD of hosts, God of Israel, hast revealed to thy servant, saying, I will build thee an house: therefore hath thy servant found in his heart to pray this prayer unto thee.
28 And now, O Lord GOD, thou art that God, and thy words be true, and thou hast promised this goodness unto thy servant:
29 Therefore now let it please thee to bless the house of thy servant, that it may continue for ever before thee: for thou, O Lord GOD, hast spoken it: and with thy blessing let the house of thy servant be blessed for ever.

John 18:36 Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence.
37 Pilate therefore said unto him, Art thou a king then? Jesus answered, Thou sayest that I am a king. To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth. Every one that is of the truth heareth my voice

Rev 19:11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
12 His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.
13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
14 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
16 And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS.

Jesus, as a son of man, was God’s greatest instrument of prayer when He walked this earth; and He is still God’s greatest instrument as He intercedes in heaven. His life on this earth was a life that was devoted to prayer. He was always seeking His Father’s face, always praying for God’s will to be done. Everything He did was the Father’s perfect will, because His whole life was dedicated to knowing, praying for, and doing the will of God. As a man, He had the right to ask God to intervene in this world; as a man, He depended upon God’s intervention; and yet as the God-man, His every prayer was heard, because He always prayed according to God’s revealed will, for He was the Word made flesh.

Matt 14:23 And when he had sent the multitudes away, he went up into a mountain apart to pray: and when the evening was come, he was there alone.

Luke 6:12 And it came to pass in those days, that he went out into a mountain to pray, and continued all night in prayer to God.

Rom 8:34 Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.

Heb 7:25 Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them.

John 11:41 Then they took away the stone from the place where the dead was laid. And Jesus lifted up his eyes, and said, Father, I thank thee that thou hast heard me.
42 And I knew that thou hearest me always: but because of the people which stand by I said it, that they may believe that thou hast sent me.

John 5:30 I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me.

John 6:38 For I came down from heaven, not to do mine own will, but the will of him that sent me.

Luke 2:49 And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business?

John 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.

It is to be through Jesus, who truly is a son of man, that the bottled up prayers of all of God’s saints will be answered. Through Him, the cries of suffering and the prayers of His people for retribution will finally be heard. The prayers of the martyrs, those that have been persecuted by ungodly men, those saints who, because of their faith in God, have endured untold agonies, will at last come up before God.  It is because Jesus prevailed upon this earth—living the life of a perfect man, and dying the perfect sacrificial death for His people; that when the time comes for the final out-pouring of God’s judgment upon this world of men—He alone will be able to open the seven-sealed book; and this He can do, not just because He is truly a man, but because He is the only man without fault—a perfect man who can pray for, and loose this final judgment.

Rev 5:1 And I saw in the right hand of him that sat on the throne a book written within and on the backside, sealed with seven seals.
2 And I saw a strong angel proclaiming with a loud voice, Who is worthy to open the book, and to loose the seals thereof?
3 And no man in heaven, nor in earth, neither under the earth, was able to open the book, neither to look thereon.
4 And I wept much, because no man was found worthy to open and to read the book, neither to look thereon.
5 And one of the elders saith unto me, Weep not: behold, the Lion of the tribe of Juda, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof.
6 And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth.
7 And he came and took the book out of the right hand of him that sat upon the throne.
8 And when he had taken the book, the four beasts and four and twenty elders fell down before the Lamb, having every one of them harps, and golden vials full of odours, which are the prayers of saints

Rev 8:3 And another angel came and stood at the altar, having a golden censer; and there was given unto him much incense, that he should offer it with the prayers of all saints upon the golden altar which was before the throne.
4 And the smoke of the incense, which came with the prayers of the saints, ascended up before God out of the angel's hand.

God has chosen to act upon this world through prayer; and much of what He does upon this earth is the result of prayer. Therefore, God is hearing the prayers and cries of every man, women, boy, and girl, both living and departed. He is hearing the cries of the aborted babies as they are cruelly torn from their mother’s wombs by the doctors of death. He is hearing the cries of the aged as they are lying upon their death bed. He is hearing the groanings of this earth and of the creatures that He loves. He is hearing the prayers of the saints and the prayers of the sinners, the voices of the Holy Angels and the voices of demons. No cry has ever escaped His ear; no prayer has ever been forgotten; and He hears and considers all them together corporally, and each one of them separately—according to His own will and purpose. He purposes for some prayers to be prayed by His saints to carry out the will of God; and He moves others to stop praying so that His will may be done. He opens His heart to the prayers of His children, and He closes it to those who reject His goodness. He sovereignly chooses which prayers He will hear and answer, and which ones He will not—to accomplish His purpose and bring about His glory.

Rom 8:22 For we know that the whole creation groaneth and travaileth in pain together until now.

Psa 147:9 He giveth to the beast his food, and to the young ravens which cry.

Job 38:41 Who provideth for the raven his food? when his young ones cry unto God, they wander for lack of meat.

Rev 6:9 And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held:
10 And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?

Jude 1:9 Yet Michael the archangel, when contending with the devil he disputed about the body of Moses, durst not bring against him a railing accusation, but said, The Lord rebuke thee.

Matt 8:28 And when he was come to the other side into the country of the Gergesenes, there met him two possessed with devils, coming out of the tombs, exceeding fierce, so that no man might pass by that way.
29 And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time?
30 And there was a good way off from them an herd of many swine feeding.
31 So the devils besought him, saying, If thou cast us out, suffer us to go away into the herd of swine.
32 And he said unto them, Go. And when they were come out, they went into the herd of swine: and, behold, the whole herd of swine ran violently down a steep place into the sea, and perished in the waters.

Jer 7:16 Therefore pray not thou for this people, neither lift up cry nor prayer for them, neither make intercession to me: for I will not hear thee.

Jer 11:14 Therefore pray not thou for this people, neither lift up a cry or prayer for them: for I will not hear them in the time that they cry unto me for their trouble.

Psa 34:15 The eyes of the LORD are upon the righteous, and his ears are open unto their cry.

Isa 59:1 Behold, the LORD's hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear:
2 But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear.

So to the question of why God’s people should pray—we pray because God has ordained for us to pray. He works in us to pray. We serve Him by praying; and He works through our prayers for His “kingdom” to “come” and His “will” to “be done in earth, as it is in heaven.”

1 Tim 2:8 I will therefore that men pray every where, lifting up holy hands, without wrath and doubting.

Phil 2:13 For it is God which worketh in you both to will and to do of his good pleasure.

Luke 2:36 And there was one Anna, a prophetess, the daughter of Phanuel, of the tribe of Aser: she was of a great age, and had lived with an husband seven years from her virginity;
37 And she was a widow of about fourscore and four years, which departed not from the temple, but served God with fastings and prayers night and day.

Rom 1:9 For God is my witness, whom I serve with my spirit in the gospel of his Son, that without ceasing I make mention of you always in my prayers;

1 Sam 12:23 Moreover as for me, God forbid that I should sin against the LORD in ceasing to pray for you: but I will teach you the good and the right way:

Matt 6:9 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
10 Thy kingdom come. Thy will be done in earth, as it is in heaven.
