Are you asking if God could be made a liar? What He has proclaimed will be. He knows all that is past, present, and future.
Are you asking if man can prevail upon Him to change His mind? There is some suggestion of that in the scriptures, yet He always knows what He is doing.
Example: Satan has set his will against God & will ultimately be dispatched to the Lake of Fire, which burns eternally. So, if I pray that Satan will repent, be reconciled to God, and return to heaven, will it happen? No, because that would make the Word of God untrue. And, God is Truth.
No, I’m not asking if God can be made a liar and no, I’m not asking if man can prevail upon Him to change His mind.
I’m suggesting that if God knows what someone will do, and what God knows will happen, must happen...then where is the free-will choice?
For an example, God knew Jeffrey Dahmer was going to commit horrible crimes before Dahmer was even born. This we’ve established. How then, could Dahmer NOT commit those crimes? Why would God create horrible people and innocent victims, knowing what will happen?
