Here’s a prayer of commitment based on the suggested scripture passages for Proper 27A (November 6, 2011).
Prayer of Commitment
(Joshua 24, Matthew 25: 1-13)
You let us choose, O God,
between you and the false gods of this world.
In the midst of the night of sin and death,
wake us from our slumber
and call us forth to greet Christ,
so that with eyes and hearts fixed on him,
we may follow to eternal light. Amen.
