“When you pray that your sins may be forgiven, strengthen yourself always by faith, and trust in God’s mercy, Who is ever ready to forgive our sins after sincere prayer, and fear lest despair should fall on your heart—that despair which declares itself by deep despondency and forced tears. What are your sins in comparison to God’s mercy, whatever they be, if only you truly repent of them?”
(St. John of Kronstadt ‘My Life in Christ’)
