My brothers, let each of you present himself before the face of the Lord, and confess his faults and sins, following my words in his heart;
O Lord God, eternal and almighty Father, we confess and acknowledge truthfully before Your holy majesty that we are poor sinners, conceived and born in iniquity and corruption, prone to do evil, incapable of any good, and that in our depravity we transgress Your holy commandments without end or ceasing; therefore, we purchase for ourselves, through Your righteous judgment, our ruin and damnation.
Nevertheless, O Lord, we are grieved that we have offended You, and we condemn ourselves and our sins with true repentance, begging Your mercy to relieve our distress. O God and Father most gracious and full of compassion, have mercy on us in the name of Your Son, our Lord Jesus Christ.
And as You blot our sins and stains, magnify and increase us day by day the grace of the Holy Spirit, that as we acknowledge our unrighteousness with all our heart, we may be moved by that sorrow that shall bring forth true repentance in us, mortifying all our sins and producing in us the fruit of righteousness and innocence that are pleasing to You, through the same Jesus Christ our Lord. Amen.
