For it is impossible that God should leave in obscurity any good work of man; but He makes it manifest in this world, and glorifies it in the next world, because it is the glory of God; as likewise the Devil manifests evil, in which is shewn the strength of his great wickedness.
But God properly makes public every good deed only in that world the goods of which are not common to the righteous and the wicked; therefore to whomsoever God shall there shew favour, it will be manifest that it was as reward of his righteousness. But the reward of virtue is not manifested in this world, in which both bad and good are alike in their fortunes.
