Those who are self-controlled refrain from gluttony; those who have renounced possessions, from greed; the tranquil, from loquacity; the pure, from self-indulgence; the modest, from unchastity; the self-dependent, from avarice; the gentle, from agitation; the humble, from self-esteem; the obedient, from quarrelling; the self-critical, from hypocrisy. Similarly, those who pray are protected from despair; the poor, from having many possessions; confessors of the faith, from its denial; martyrs, from idolatry. Do you see how every virtue that is performed even to the point of death is nothing other than refraining from sin? Now to refrain from sin is a work within our own natural powers, but not something that buys us the kingdom.
