O Lord God, heavenly Father,
we praise and thank you for your grace
that through your Son Jesus Christ
you established this supper
in which we eat his body and drink his blood.
By your Holy Spirit, help us
to use this gift worthily,
to confess and forsake our sins,
to confidently believe that we are forgiven through Christ,
and to grow in faith and love day by day
until we come at last to the joy of eternal salvation,
through Jesus Christ, your Son, our Lord.
