Here is a simple Call to Worship we will use this week, from Psalm 27:

Yahweh is my light and my salvation—whom shall I fear?
Yahweh is the stronghold of my life—of whom shall I be afraid?

One thing I ask from of Yahweh, this only do I seek:
to dwell in the house of Yahweh all the days of my life,
to gaze on the beauty of the LORD
and to seek God in the holy temple.
God will hide me in the shelter of the sacred tent.
I will sing and make music to Yahweh.

Your face, O God, I will seek.
Wait for Yahweh.
Be strong and take heart and wait for Yahweh.
