Aurelius Answers, If God Cannot Save Some Sinners, Because They Have Free Will, Can We Truly Say He Is Omnipotent?

There are a few different things happening here, Gods omniscience has nothing to do with His ability to make people do things if it serves His will. There is also the advent of free will that God will not go against. There is an account in scripture where God hardened the heart of the Pharaoh of Egypt preventing him from letting the children of Israel go before God was able to demonstrate his wonders to Israel.

"Thou shalt speak all that I command thee: and Aaron thy brother shall speak unto Pharaoh, that he send the children of Israel out of his land. And I will harden Pharaoh's heart, and multiply my signs and my wonders in the land of Egypt. But Pharaoh shall not hearken unto you, that I may lay my hand upon Egypt, and bring forth mine armies, and my people the children of Israel, out of the land of Egypt by great judgments". Exodus 7:2-4

The purpose of the Judgment and salvation in the first place is for those who Love God and want to be in relationship with Him. God knows who has a heart for Him, and those who don’t. We were not created as robots but with free will, as were the Angels who also have free will. God does not MAKE us worship Him, we have to choose it. There is a difference between what God knows and can do and what He will do and why He does what He does.

"The Lord is not slack concerning his promise, as some men count slackness; but is long suffering to us-ward, not willing that any should perish, but that all should come to repentance." 2 Peter 3:9

If you could force a person to love you it would not be as fulfilling if they loved you of their own free will. That is the point of choice.

What we should understand about God in part, is that His powers are unlimited, and yet He exercises restraint, mercy, patience, forgiveness, love, understanding and grace among other things to us when we deserve none of it. That is the difference between a just God and us. With all His power, He lets us make the choice.
