John Chrysostom

Many of the more careless sort, using the loving kindness of God to increase the magnitude of their sins and the excess of their disregard, speak in this way, saying: There is no hell, no future punishment. God forgives all our sins.

Max Muller

I have always held that it would be a miserable universe without eternal punishment. Every act, good or evil, must carry its consequences. and the fact that our punishment must go on forever seems to me a proof of the everlasting love of God. For an evil deed to go unpunished would be to destroy the moral order of the universe. … Without eternal punishment we should have no touch with God, the world would be Godless, God-forsaken.
