As a spiritual father I advise you, whenever you sin, to be careful not to despair but to run to the spiritual doctor to confess and seek a cure: the mercy of God. The Lord came into the world to save not the righteous, those who are healthy in soul, but the sinners, those who are ill. He will receive these with great love and mercy as He received the prodigal son, the prostitute, the thief, the publican, and millions of sinners who were saved by repentance and confession. I leave you this paternal counsel: never, never despair whenever you sin, but have confidence and hope in the immeasurable mercy of God. Repent and confess, and you will be saved. The grace, peace, mercy and bless of God, the protection and aid of the Virgin Mary and of all the saints, and my blessing be with you.
–Philotheos Zervakos (1884-1980)
