Psalm 103:12 As far as the east is from the west, so far has He removed our transgressions from us. Isaiah 43:25 "I, even I, am the one who wipes out your transgressions for My own sake, And I will not remember your sins.
He bore our sins on His body and He took them to the grave when He died and there they remain and when God removes death forever sin will be gone forever too.
If God doesn't remember our sins, why is there hell? Heck, why is there hell to begin with?
