If then it is the soul which, first and especially, is that which is to live, and if virtue springing up around it saves, and vice kills; then it is clearly manifest that by being poor in those things, by riches of which one destroys it, it is saved, and by being rich in those things, riches of which ruin it, it is killed. And let us no longer seek the cause of the issue elsewhere than in the state and disposition of the soul in respect of obedience to God and purity, and in respect of transgression of the commandments and accumulation of wickedness.
