Thus far we have disputed concerning the virtue whose name is fortitude. Let us now see what aid justice also brings us in this life, and how it too, in the hearts of those who have given themselves to it, can be overcome by no assaults of the vices. For faith, which is the foundation of justice, which no good works precede, and from which all good things proceed, itself purges us from all sins, enlightens our minds, reconciles us to God, and associates us with all sharers of our nature; inspires in us the hope of future recompense, increases in us the holy virtues, and confirms us in their possession.
