I think it may have been overlooked here that it is not really God who is changing God's mind but man who is directing the hand of God in one direction or the other. Let's take Jer. 18:8 for example:
"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."
We see here where God's mind is fixed on 2 courses of action, and it is man who will determine if God repents from the course He first spoke of. The same is true in salvation. God has determined to condemn man for sin, but if man repents and turns to God, then God will 'repent' and turn to man.
Look at Jonah 4:2, where Jonah bemoaned the fact that God turned from the judgment He had pronounced upon Ninevah when the city repented:
"And he prayed... for I knew that thou art a gracious God, and merciful, slow to anger, and of great kindness, and REPENTEST thee of the evil"
Is this really a God of love and compassion, not willing that any of the wicked should refuse to be saved and perish? Yes, indeed, that is our God of love! If a sinner refuses to turn to God, however, in spite of that which God does for him, lightening him with the Word of Truth, and drawing him with all men to Christ lifted up on the cross, then there will be no 'repentance' or turning away from the decreed judgment by God toward that willful rebel.
Good post, and maintains truth about the Nature of God, but of course a "determinist" will have to reject it because it doesn't fit his boxed system, and if he has nothing to rationally respond to he'll probably just dismiss it by accusing of you making MAN God. Don't have time to get into this but wanted to pass by with the :thumbs:.
