I don't debate with Open Theists. You won't listen, anyway. I will just say you're wrong and move on.
		
		
	 
Something wrong with Open Theism?
If God can't change His plans and promises, then why does Job 34:14-15 imply so?
Job 34:14-15 "If He should 
determine to do so,
         If He should gather to Himself His spirit and His breath, 
    All flesh would perish together,
         And man would return to dust.
God has promised a bright future for mankind yet this Scripture shows He can change His mind about mankind's future anytime He wishes.
By saying God can't change His mind about something, you are setting a limit on Him. God can do whatever He wishes.
Of course, God does not change His promises (James 1:17; John 6:37).
John 6:37 "All that the Father gives Me will come to Me, and the one who comes to Me I will 
certainly not cast out. 
Rather, He changes His plans.
For example, God might not cast out the one who comes to Him, but He had planned to use the person in a powerful way to accomplish His purposes but because the person did not repent, He changed His plans for that person and uses him like any other pastor to this day.
Is God capable of changing His mind, His promises, and His plans? According to the Scriptures, yes.
But does God always change His plans? Not entirely if they are promises.
Does God change His promises? No.
But can He delay them? Yes, as seen in the OT, in which He delays Israel's entry into the promised land because of their disobedience.
