we cant change Gods mind is my understanding, doesn't matter what we say, or do prayer is about trust.
And we have to trust God knows all things and he knows his plan for all humanity.
For us to change Gods mind means we have to change his plan, I believe exactly like the understanding in the lecture, by a well put together educated lecture, For us to change Gods mind we would have to be God himself. It's about God changing our minds
What you believe is irrelevant to what is true. The Bible gives accounts of God changing His mind. God Himself says that He changes His mind. But because those facts do not agree with the God you imagine in your mind, you reject those scriptures and invent some incoherent philosophical work-around to justify your rejection of what God straight-forwardly tells us about Himself.
Jer. 18:5 Then the word of the Lord came to me, saying,
6 O house of Israel, cannot I do with you as this potter? saith the Lord. Behold, as the clay is in the potter's hand, so are ye in mine hand, O house of Israel.
7 At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy it;
8 If that nation, against whom I have pronounced, turn from their evil, I will repent of the evil
that I thought to do unto them.
9 And at what instant I shall speak concerning a nation, and concerning a kingdom, to build and to plant it;
10 If it do evil in my sight, that it obey not my voice, then I will repent of the good,
wherewith I said I would benefit them.
11 Now therefore go to, speak to the men of Judah, and to the inhabitants of Jerusalem, saying, Thus saith the Lord; Behold, I frame evil against you, and devise a device against you: return ye now every one from his evil way, and make your ways and your doings good.
