My understanding is that Calvinists believe God's predestination is based on the sovereign choice of an Almighty God completely independent of the will of the believer or any other criteria. and that Arminians believe that God's predestination is based on God's knowing who would be saved beforehand (or his foreknowledge). Is that the 2 positions relative to this doctrine in a nutshell, or am I misunderstanding something? If the Calvinist position is correct as I have hopefully correctly stated, then how does one explain 1 Peter 1:2, and Romans 8:29, especially the ideas of elect according to the foreknowledge of God and God's predestinating those he foreknew? If the Calvinist position is correct then why doesn't that conflict with God's promise that there will be no respect of persons with God (Romans 2:11)?
