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.

It is harmful to remember previous sins in detail. For if they bring you sorrow, they will estrange you from hope, but if they are remembered without sorrow, they will introduce the previous defilement. If you want to bring to God an uncondemned confession, then don't remember your sins in detail, but manfully endure the suffering that is coming because of them.

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.

He who seeks forgiveness of his sins loves humility, but if he condemns another he seals his own wickedness.

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.

Consistently pray in all things, so that you might not do anything without the help of God ... Whoever does or busies himself with anything without prayer does not succeed in the end. Concerning this, the Lord said: "Without Me you can't do anything". (John 15:5)

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.
