O Lord, our God, pre-existing before all ages and remaining forever; who are as great in compassion as you are in uncontainable power; who because of your ineffable mercy bowed the heavens, came down on earth and became man for the salvation of sinners; who put on and immortalized our nature and ascended with it to the place from which you descended; hear from heaven and become merciful to all those who cry out to you with a broken heart. You, O Master of all, lend you ear and hear us. We know your undefeatable love for your creation and your inexhaustible goodness. Hence, we throw ourselves into the ocean of your compassions and entreat you: turn not your face from us nor cast us away from your countenance neither hand us over to those who are so furiously attacking us. Look upon us with your compassionate eye. Show us how to rise above both the visible and invisible enemies. Place in us a power from on high; encompass us with your almighty right hand; keep us under the protection of your wings; fortify us with love for one another and grant us unshakable peace. But before all and above all, instill in us your fear and your love that your holy name may also be glorified in us. Upon you alone we look, on you alone we have placed our hopes, and to you we send up the glory, together with your Father, who is without beginning, and the life-creating Spirit, now and ever and unto the ages of ages. Amen.
