One who has sinned cannot escape retribution in any other way than by repentance corresponding to his sin.

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)

Whoever does not fight the one who despises him, neither in word not in thought, has received true knowledge and demonstrates a firm trust in God.

Do not try to decide a difficult matter by means of disputing, but that which is enjoined by the spiritual law, namely patience, prayer, and thoughtful hope.

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.

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