Conquer temptations by the patience and prayer. If you oppose them without these, you will fall all the more severely.

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.

When the mind forgets the purpose of Christian life, then even the clear fulfillment of virtue becomes profitless.

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.

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.

Every sin that is left without repentance is a sin unto death, for which if even a saint shall pray, he shall not be heard.

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