Litany Prayer for True Worship

O God,
you have commanded us to worship you in spirit and in truth.
Overshadow us with the power of your Holy Spirit.
Let your mercy and the gracious promise of your salvation come to us,
that our prayer may be directed to you by Christ,
through whom our sins are forgiven.
Hear us, O Lord. Amen.
