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.

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

Do not attempt to benefit by rebukes one who boasts of his virtues, for he loves to display himself can not be a lover of truth.

Whoever has a spiritual gift and compassionate toward one who does not have it guards his gift through his compassion. But whoever is proud of his gift loses it through self-opinion.

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.

We must receive the one who curses us as a messenger from God, rebuking our hidden evil thoughts, so that we, seeing our thoughts with exactness, might correct ourselves. For we do not know how many hidden evils we have; Only a perfect man can understand all of his own shortcomings.

No one is as good and merciful as the Lord. But even He does not forgive the unrepentant.
