Grant, we beseech thee, Almighty God, that like as we do believe thy only-begotten Son our Lord Jesus Christ to have ascended into the heavens; so we may also in heart and mind thither ascend, and with him continuously dwell, who liveth and reigneth with thee and the Holy Ghost, one God, world without end. Amen.
