Sin and suffering are not natural opposites. The opposite of evil is good, not suffering. The opposition of sin is not suffering, but righteousness. The path across the gulf that divides right from wrong is not the fire, but repentance.
If my friend has wronged me, will it console me to see him punished? Will that be a rendering to me of my due? What kind of friendship would I be ft for if that were possible, even with regard to my enemy? But would not the shadow of repentant grief, the light of reviving love on his face, heal it at once, however deep the hurt had been?
