Barring my faulty memory (and if I’m not lazy) I want to post prayers on Monday from all over Church History and then throughout the modern day, and then my own. This one comes from Myriobiblos, the Orthodox Prayer Book.
O All-wise and All-gracious Lord, Our Saviour, Who didst enlighten all the ends of the world by the radiance of Thy Coming, and Who didst call us into Thy Holy Church through the promise of the inheritance of incorruptible and eternal good! Graciously look down on us, Thy worthless servants, and remember not our iniquities, but according to Thy infinite mercies forgive all our sins. For though we transgress Thy holy will, we do not deny Thee, Our God and Saviour. Against Thee alone do we sin, yet Thee alone do we serve, in Thee alone do we believe, to Thee alone do we come, and Thy servants only do we wish to be. Remember the infirmity of our nature and the temptations of the adversary and the worldly enticements and seducements which surround us on all sides, and against which, according to Thy word, we can do nothing without Thy help. Cleanse us and save us! Enlighten our minds that we may firmly believe in Thee, our only Saviour and Redeemer! Inspire our hearts that we may wholly love Thee, our only God and Creator! Direct our steps that we may unstumblingly walk in the light of Thy commandments! Yea, our Lord and Creator, show us Thy great and abundant kindness, and make us live all the days of our life in holiness and truth, that at the time of Thy glorious Second Coming, we may be worthy to hear Thy gracious call into Thy Heavenly Kingdom. Grant us, Thy sinful and unprofitable servants, to receive Thy Kingdom, and that in the enjoyment of its ineffable beauty, we may ever glorify Thee, together with Thy Eternal Father and Thy Ever-living Divine Spirit to the ages of ages. Amen.
