God the Father, God the Son, and God the Holy Spirit
bless, preserve, and keep us.
The Lord mercifully with look on us with his favor,
and fill us with all spiritual benediction and grace,
that we may live godly, righteously, and soberly in this life,
and in the world to come we may have life everlasting.
