One evil receives strength from another. In the same way, good deeds also sprout one from another, and the one in whom they are found grows larger.

We cannot with all our heart forgive someone who does us wrong unless we possess real knowledge. For this knowledge shows us that we deserve all we experience.

Guard your mind from self-praise and flee a high opinion of yourself, so that God does not allow you to fall into the opposite passion to the virtue for which you boast, for man does not accomplish virtue alone, but with the help of God who sees all.

A man who hates the passion cuts off their causes. But a man who remains among their causes experiences even against his will the conflict from the passions. It is not possible to be mentally inclined toward a passion if one does not love its cause. For who, disdaining shame, is given to vainglory? Or who, loving lowliness, is bothered by dishonor? Who, having a broken and humble heart, accepts fleshly sweetness? Or who, believing in Christ, is concerned about temporal things, or argues about them?

Because God's justice is inexorable, it is hard to obtain forgiveness for sins committed with complete deliberation.

The devil makes small sins seem smaller in our eyes, for otherwise he can't lead us to greater evil.

Whoever with fear of God corrects and directs a sinner gains virtue for himself, that of opposition to sin. But whoever insults a sinner with rancor and without good will falls, according to a spiritual law, into the same passion with the sinner.
