Son of God,
Lord Jesus Christ,
crucified on a cross for us
and raised up from the grave,
to you we pray.
Receive us into your eternal church
and keep us always.
With your Holy Spirit, guide us
in the light of your Word.
The almighty God,
Father of our Lord and Savior, Jesus Christ,
mercifully protect you,
and guide you.
May the almighty God,
Father of our Savior Jesus Christ,
who through his gospel is gathering
an eternal church among men and women,
strengthen you in body and soul,
and graciously keep and guide you,
now and forever.
