Evening Prayer of St Macarius the Great
St Macarius the Great (300–391) was one of the Desert Fathers of Egypt. This evening prayer is part of the standard Orthodox evening prayer rule.
O Eternal God and King of all creation, Who hast granted me to arrive at this hour, forgive me the sins that I have committed today in deed, word, and thought, and cleanse, O Lord, my humble soul from all defilement of flesh and spirit.
And grant me, O Lord, to pass the sleep of this night in peace, that when I rise from my humble bed I may please Thy most holy Name all the days of my life and conquer the enemies, both fleshly and spiritual, that war against me.
And deliver me, O Lord, from vain thoughts that stain me, and from evil desires.
For Thine is the kingdom, and the power, and the glory, of the Father, and of the Son, and of the Holy Spirit, now and ever and unto ages of ages. Amen.
