One of the wonderful things about knowing God is that there is certainly a beginning, but there is no end. It just may be that when Satan fell, he did so because he thought that he knew God fully. Satan seemed to be counting on just the righteousness and justice of God. He did not grasp the mercy and grace of God, and most certainly he will never grasp it. For that he fell and can never be redeemed. And it is for this reason that sinful man can be redeemed, and saved, for he discovers the love, grace, and mercy of God.
This program is already assigned to that list.
