People who go to hell do so because they reject God. Once they are in hell they do not ask for forgiveness because they reject the very existence of God.
That’s another verse of Scripture that people who advocate for U/S ignore.
Paul expresses the difference between our knowledge here on earth and our knowledge in eternity.
He says that here we see, “as through a glass darkly,” but there we will see fully.
He says here we know partially. Then he says “then”, meaning in eternity, we will know fully as we are known.
We receive mercy from God in this life because of the weakness of our wounded natures due to original sin.
We inherited this from Adam and Eve as a state, not an act.
We receive mercy from God in this life due to our ignorance. We must accept God’s love and forgiveness and work to conquer our tendency to sin through a life in relationship with God and receiving His grace to overcome our weakness.
After death, if we have refused God’s mercy and forgiveness, either through pride of arrogance (I’m a good person and don’t need to be forgiven), or pride of despair(I’m so sinful and wretched that God could never forgive the likes of me), they will enter eternity with those choices ingrained into their wills because they chose to believe themselves over and against God.
Those who insist, “I’m a good person and don’t need to be forgiven,” will never ask for God’s forgiveness; and God will let them have it their way. Thus they will wind up in hell.
Those who say,“my sins are so terrible and wretched that God won’t ever forgive me,” will never ask for God’s forgiveness either; and God will let them have it their way. Thus they will wind up in hell.
Its really that simple.
