The Aposticha Prayers for the Vespers on Thursday Evening of the 3rd Week of Great Lent:
O Christ our God, the life of all, You were hung upon the Cross: restore life to my soul, slain by my sins. Do not allow Your sheep to perish completely, O Good Shepherd. I have rebelled against Your commandments, and through my willful live of sin, I have wasted the wealth of innocence that You gave me. Living like the Prodigal, I have grown corrupt and loathsome. But bring me to repentance and renew me, for You alone are full of mercy.
Your martyrs, O Lord, did not deny You, nor did they fall away from Your commandments. At their intercession, have mercy on us.
