Wisdom and prayers of saints

We bless you, O God, most high and Lord of mercy. You are always doing great and inscrutable things with us, glorious and wonderful, and without number. You grant us sleep for rest from our infirmities, and repose from the burdens of our much toiling flesh. We thank you, for you have not destroyed us with our sins, but have continued to love us; and though we were sunk in despair, you have raised us up to glorify your power. Therefore, we implore your incomparable goodness. Enlighten the eyes of our understanding and raise up our minds from the heavy sleep of indolence. Open our mouth and fill it with your praise, that we may be able without distraction to sing and confess that you are God, glorified in all and by all, the eternal Father, with your only begotten Son, and your all holy, good, and life giving Spirit, now and forever and to the ages of ages. Amen.
