Collect for the Ascension Day

Almighty God, whose blessed Son our Savior Jesus Christ ascended far above all heavens that he might fill all things: Mercifully give us faith to perceive that, according to his promise, he abides with his Church on earth, even to the end of the ages; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, in glory everlasting. Amen.

or this

Grant, we pray, Almighty God, that as we believe your only-begotten Son our Lord Jesus Christ to have ascended into heaven, so we may also in heart and mind there ascend, and with him continually dwell; who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
