Call to Worship, Ascension Sunday, Year C

Friends, why do you stand looking up toward heaven?
Come and experience the risen Christ,
alive and at work among you!
Come, and wait for the promise of the Creator --
the Spirit that hovered over the waters
baptizing you by its power.
Come, for you have been witnesses ...
you are witnesses ... 
you will be witnesses
to the ends of the earth.
Come and worship God!
