Prayer for Last week of Epiphany

O God, who before the passion of your only-begotten Son revealed his glory upon the holy mountain: Grant us that we, beholding by faith the light of his countenance, may be strengthened to bear our cross, and be changed into his likeness from glory to glory; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, on God, for ever and ever. Amen.
