Prayer is an integral part of Orthodox spirituality. Listed below are some prayers that are used by Orthodox Christians.
Having risen from sleep, we fall down before Thee, O Good One, and we cry aloud to Thee the angelic hymn, O Mighty One: Holy, Holy, Holy art Thou, O God; through the Theotokos, have mercy on us.
Glory to the Father, and to the Son, and to the Holy Spirit: From bed and sleep hast Thou raised me up, O Lord; enlighten my mind and heart, and open my lips that I may hymn Thee, O Holy Trinity: Holy, Holy, Holy art Thou, O God; through the Theotokos, have mercy on us.
Both now and ever, and unto the ages of ages. Amen. Suddenly the Judge shall come, and the deeds of each shall be laid bare; but with fear do we cry at midnight: Holy, Holy, Holy art Thou, O God; through the Theotokos, have mercy on us.
Lord, have mercy (12 times).
A prayer of St. John Chrysostom
Prayer before receiving communion
I believe, O Lord, and I confess that thou art truly the Christ, the Son of the living God, who didst come into the world to save sinners, of whom I am chief. And I believe that this is truly thine own immaculate Body, and that this is truly thine own precious Blood. Wherefore I pray thee, have mercy upon me and forgive my transgressions both voluntary and involuntary, of word and of deed, of knowledge and of ignorance; and make me worthy to partake without condemnation of thine immaculate Mysteries, unto remission of my sins and unto life everlasting. Amen. Of thy Mystic Supper, O Son of God, accept me today as a communicant; for I will not speak of thy Mystery to thine enemies, neither will I give thee a kiss as did Judas; but like the thief will I confess thee: Remember me, O Lord, in thy Kingdom. Not unto judgement nor unto condemnation be my partaking of thy Holy Mysteries, O Lord, but unto the healing of soul and body.
And now as we lay down to sleep, O Master, grant us repose both of body and of soul, and keep us from the dark passions of the night. Subdue Thou the assaults of passions. Quench the fiery darts of the Wicked One which are thrown insidiously at us; calm the commotions of our flesh and put away all thoughts about worldly and material things as we go to sleep. Grant us, O god, a watchful mind, chaste thoughts, a sober heart, and a gentle sleep, free from all the fantasies of Satan. And raise us up again at the hour of prayer, established in Thy commandments and holding steadfast within ourselves the remembrance of Thy judgments. Give us the words of Thy glorification all night long, that we may praise, bless, and glorify Thy most honorable and magnificent name, O Father, Son and Holy Spirit, now and ever, and unto ages of ages. Amen.

“In spite of our sinfulness, in spite of the darkness surrounding our souls, the Grace of the Holy Spirit, conferred by baptism in the name of the Father and the Son and the Holy Spirit, still shines in our hearts with the inextinguishable light of Christ … and when the sinner turns to the way of repentance the light smooths away every trace of the sins committed, clothing the former sinner in the garments of incorruption, spun of the Grace of the Holy Spirit. It is this acquisition of the Holy Spirit about which I have been speaking. ”
