Does Prayer Change God's Mind?

I am slowly inching my way through Deuteronomy, when I came across this question in my Bible.
Here's the answer: "Though most believe the Bible affirms that God know beforehand what we will ask and how He will answer, it is spiritually beneficial for us to pray. Moses interceded on behalf on the people, and God, wanting to forgive, heard his prayer. Yet it seems that God would have destroyed the people, if Moses didn't stand up for them. This is the part if the mystery of how human activities relates to God's sovereignty." (Quest Bible-Deut. 9:19).

So why pray? Can God change his mind? (Question from Quest Bible) Answer: " Scripture teaches us that God does not change his mind, but sometimes adjusts his answer to fit our response. The Bible contains many examples of this. (Numbers. 14:11-23; 29:19; 1 Samuel 15:29); Hezekiah's repentance on behalf of Israel (2Chron. 29:3-10,36) and the sparing of Nineveh ( Jonah 3:1-10).

Experiencing God's will is dynamic. As with any interpersonal relationship, God's relationship with humanity involves unexpected twists and turns. God modifies his responses to ours; we adjust our responses to God's. So, in a sense, it can be said that God sometimes changes his mind in response to our prayers.

At the same time, God's will is determined. There are decrees and promises he has made that do not change. He kept his covenant with the Israelites( Deut. 7:7-8) and keeps his new covenant with those who believe in Jesus(John 6:37-40,44).

God wants us to do his will obediently. He has predetermined ways he expects us to respond, but he has made us capable of resisting him (Ps. 143:10; 1 Thes. 5:16-18; Heb. 10:35-39; 2 Peter 3:9).

These aspects of God's will work together. It is not possible for us to understand exactly how they work together, but God is ultimately in control. We might compare the relationship between God, his will and his people to a chess match between a novice player and a master. The novice can make any move he chooses and the master will respond accordingly. But the master will always be in control of the game. This analogy is limited and should not be pressed to far, but God's people "win" when the Master's will is done." (Quest Bible Exodus 32:14).

My thoughts:
Prayer is a daily reminder that we are not in control. When we try to be in control, we can mess up God's original plan for us. We can make life so much harder for ourselves when we choose not to listen.

What if Moses had never begged for mercy on the Israelites? Would history have been rewritten? I think there are some questions we won't get answers to. I know some people say that you can ask when you get to Heaven, but I doubt I'll care once I am there.
