From the Liturgy of the Presanctified Gifts…

O Almighty Lord, who hast made all created things in wisdom, and by Thine inexpressible providence and great goodness hast brought us to these all-holy days, for the purification of body and soul, for the controlling of carnal passions, and for the hope of the Resurrection; who, during the forty days didst give into the hands of Thy servant Moses, the Tablets of the Law in characters Divinely traced by Thee; Enable us also, O Good One, to fight the good fight; to accomplish the course of the Fast; to preserve inviolate the Faith; to crush under foot the heads of invisible serpents; to be accounted victors over sin; and uncondemned to attain unto and adore Thy Holy Resurrection. For blessed and glorified is Thine all-honorable and majestic Name: of the Father, and of the Son, and of the Holy Spirit: now and ever, and unto ages of ages. Amen.
