Yall are making this more complicated than it is. God desires the one thing that he cannot create, the one thing that identifies most with his dominate character - Love. That is the sole reason for our existence. And, you cannot force someone to love you.
God's requirement for entry into his family is to be without sin. He is the creator and owns it all, so he gets to set the terms. For the sole purpose of creating the possibility of love, God took on flesh and died a horrible death vicariously for everyone who ever lived, everyone who wants it. Lots of people only want to enjoy all the cool stuff God made, kinda like a spoiled brat who doesn't want to work but just relax on Daddy's yacht. They like daddy's money, but don't really want him around cramping their lifestyle.
God still gives them lots of good stuff while they enjoy everything he made.... mountians, oceans, forests, friends, children, puppies, art etc. When they inevitably die because of being separated from the sole Source of Life in the universe, he still grants them what they desire most, eternal freedom from himself.
Those that allow God to supernaturally make them sinless, get to enjoy the most precious thing they could possibly imagine - the person, character, majesty and creative genius of God himself. For the believer, God is by far the greatest gift of all. When you get him, you get literally everything imaginable.
In the end, everybody gets what they want. Why is this so difficult for people to understand?
