Does prayer change God's mind?
God does not change, but He does relate to us in real time, and Scripture repeatedly shows prayer changing what happens. Several prayers in the Bible are answered by an evident turn in God's announced course, and Jeremiah teaches that God's word of warning or promise is conditioned on how people respond. Prayer does not move an unmoved God; it is the appointed means by which a loving God does His moving work.
This question arose from studying Why pray 'your will be done' if God already has a will? and Does God change His mind?.

What the Scripture says
God is unchangeable in His character
Malachi records the ground of all hope: 'I, Yahweh, don't change; therefore you, sons of Jacob, are not consumed,' and Balaam confesses that God 'is not a man, that he should lie... Has he spoken, and will he not make it good?' James adds that with the Father of lights there is 'no variation, nor turning shadow.' God's nature, His promises, and His love do not fluctuate like moods. That is why prayer is possible at all: we plead with a Person who keeps His word.
“For I, Yahweh, don’t change; therefore you, sons of Jacob, are not consumed.
God is not a man, that he should lie, nor the son of man, that he should repent. Has he said, and will he not do it? Or has he spoken, and will he not make it good?
Every good gift and every perfect gift is from above, coming down from the Father of lights, with whom can be no variation, nor turning shadow.
Yet Scripture shows prayer changing what was announced
After the golden calf, God told Moses He would consume Israel, but Moses pleaded, and 'Yahweh repented of the evil which he said he would do to his people.' Hezekiah was told, 'You will die, and not live,' and after his prayer God answered, 'I have heard your prayer. I have seen your tears. Behold, I will add fifteen years to your life.' Jeremiah's rule explains it: when a nation I spoke to destroy turns from its evil, then 'I will repent of the evil that I thought to do to them.' The announced sentence and the promised blessing are both real, and both are conditioned on the response.
Now therefore leave me alone, that my wrath may burn hot against them, and that I may consume them; and I will make of you a great nation.” Moses begged Yahweh his God, and said, “Yahweh, why does your wrath burn hot against your people, that you have brought out of the land of Egypt with great power and with a mighty hand? Why should the Egyptians speak, saying, ‘He brought them out for evil, to kill them in the mountains, and to consume them from the surface of the earth?’ Turn from your fierce wrath, and repent of this evil against your people. Remember Abraham, Isaac, and Israel, your servants, to whom you swore by your own self, and said to them, ‘I will multiply your seed as the stars of the sky, and all this land that I have spoken of I will give to your seed, and they shall inherit it forever.’” Yahweh repented of the evil which he said he would do to his people.
In those days was Hezekiah sick and near death. Isaiah the prophet, the son of Amoz, came to him, and said to him, “Thus says Yahweh, ‘Set your house in order, for you will die, and not live.’” Then Hezekiah turned his face to the wall and prayed to Yahweh, and said, “Remember now, Yahweh, I beg you, how I have walked before you in truth and with a perfect heart, and have done that which is good in your sight.” Hezekiah wept bitterly. Then Yahweh’s word came to Isaiah, saying, “Go, and tell Hezekiah, ‘Thus says Yahweh, the God of David your father, “I have heard your prayer. I have seen your tears. Behold, I will add fifteen years to your life.
At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up and to break down and to destroy it; if that nation, concerning which I have spoken, turn from their evil, I will repent of the evil that I thought to do to them. At what instant I shall speak concerning a nation, and concerning a kingdom, to build and to plant it; if they do that which is evil in my sight, that they not obey my voice, then I will repent of the good, with which I said I would benefit them.
Tell them, As I live, says the Lord Yahweh, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live: turn, turn from your evil ways; for why will you die, house of Israel?
God has appointed prayer as a real means, not a formality
James points to Elijah, 'a man with a nature like ours,' who prayed and no rain fell for three years and six months, and prayed again and the sky gave rain; he concludes that 'the insistent prayer of a righteous person is powerfully effective.' Jesus tells the parable of the persistent widow so that His disciples should always pray and not give up, promising that God will avenge His chosen ones 'who are crying out to him day and night.' If prayer were a theater, these texts would be a cruel joke; they are the Father's invitation to be part of His work.
Confess your offenses to one another, and pray for one another, that you may be healed. The insistent prayer of a righteous person is powerfully effective. Elijah was a man with a nature like ours, and he prayed earnestly that it might not rain, and it didn’t rain on the earth for three years and six months. He prayed again, and the sky gave rain, and the earth produced its fruit.
He also spoke a parable to them that they must always pray, and not give up, saying, “There was a judge in a certain city who didn’t fear God, and didn’t respect man. A widow was in that city, and she often came to him, saying, ‘Defend me from my adversary!’ He wouldn’t for a while, but afterward he said to himself, ‘Though I neither fear God, nor respect man, yet because this widow bothers me, I will defend her, or else she will wear me out by her continual coming.’” The Lord said, “Listen to what the unrighteous judge says. Won’t God avenge his chosen ones, who are crying out to him day and night, and yet he exercises patience with them? I tell you that he will avenge them quickly. Nevertheless, when the Son of Man comes, will he find faith on the earth?”
saying, “Father, if you are willing, remove this cup from me. Nevertheless, not my will, but yours, be done.”
Prayer also changes us
When we pray, we step into the presence of the One who is sovereign and good, and the shape of our wanting is re-formed. Jesus prayed in Gethsemane, 'Father, if you are willing, remove this cup from me. Nevertheless, not my will, but yours, be done,' and He walked to the cross. Paul prayed three times for the removal of his thorn and received grace sufficient to bear it, discovering that weakness is where Christ's power rests. Prayer rarely leaves us where it found us, because it first turns us toward the One who is the answer.
saying, “Father, if you are willing, remove this cup from me. Nevertheless, not my will, but yours, be done.”
By reason of the exceeding greatness of the revelations, that I should not be exalted excessively, there was given to me a thorn in the flesh, a messenger of Satan to torment me, that I should not be exalted excessively. Concerning this thing, I begged the Lord three times that it might depart from me. He has said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Most gladly therefore I will rather glory in my weaknesses, that the power of Christ may rest on me. Therefore I take pleasure in weaknesses, in injuries, in necessities, in persecutions, in distresses, for Christ’s sake. For when I am weak, then am I strong.
In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus.
But he gives more grace. Therefore it says, “God resists the proud, but gives grace to the humble.”
Both are true: His will is wise, and our asking matters
There is no contradiction, because God's will is not a rigid list but a wise plan that includes our prayers. Jesus says, 'Keep asking, and it will be given you,' for the Father gives good gifts to those who ask, and the Spirit Himself helps our weakness, making intercession for us with groanings that cannot be uttered. So pray with confidence: the God who does not change has chosen to answer the cries of His children, and He has never failed anyone who cast their cares on Him.
“I tell you, keep asking, and it will be given you. Keep seeking, and you will find. Keep knocking, and it will be opened to you.
If you then, being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask him?”
In the same way, the Spirit also helps our weaknesses, for we don’t know how to pray as we ought. But the Spirit himself makes intercession for us with groanings which can’t be uttered. He who searches the hearts knows what is on the Spirit’s mind, because he makes intercession for the saints according to God.
casting all your worries on him, because he cares for you.
Thus says Yahweh, the Holy One of Israel, and his Maker: “You ask me about the things that are to come, concerning my sons, and you command me concerning the work of my hands!

Yahweh repented of the evil which he said he would do to his people.
At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up and to break down and to destroy it; if that nation, concerning which I have spoken, turn from their evil, I will repent of the evil that I thought to do to them.
“For I, Yahweh, don’t change; therefore you, sons of Jacob, are not consumed.
