Indifference to sin is a moral blemish, and he who hates it not is a moral leper. How could He who is the Sum of all excellency look with equal satisfaction upon virtue and vice, wisdom and folly? How could He who is infinitely holy disregard sin and refuse to manifest His 'severity' (Rom. 9:12) toward it? How could He who delights only in that which is pure and lovely, loathe and hate not that which is impure and vile? The very nature of God makes Hell as real a necessity, as imperatively and eternally requisite as Heaven is. Not only is there no imperfection in God, but there is no perfection in Him that is less perfect than another.
