God’s love is all those things but it can only accept one end goal and still stay love. Someone who refuses all God’s love to the end because they think it is so wonderful to refuse to countenance the idea of God (how many children are atheists? this is usually a conceit that is schooled into youth) will be left with hate. And that is what hell is. It is a realm of hate. If the approaches to hell that God arranges for such a person within this life are not enough to get the person to call upon God, nothing will be enough. I think they’ll prefer the idea of staying in that place to the idea of ever being in heaven, so enthralled with hate at the God of heaven they will be.
Some of your remarks are valid, but some atheists might sincerely not know all you said.
But God knows their hearts, and he will judge accordingly.
