Prayer for the Forgiveness of Forgotten Sins

Lord and Master, human memory is weak; I may have forgotten some of my sins and not confessed them, therefore to You, the One‑Hearted, I pray: You forgive me all because of Your love for man. Thus is shown the greatness of Your glory, that You do not repay sinners for their sins, for You are praised forever and ever.
Lord, grant me the Spirit of humility, that I may be gentle and restrained from anger toward my neighbors. Grant me the Spirit of meekness, that I may not be boastful nor exalt myself above others, and not be proud or haughty. Amen.
