Opening Litany
(based on Isaiah 9: 2)
The people walking in darkness have seen a great light.
Come, O Lord, and send us your light.
O come, O come, Immanuel.
Come and bring the light of God.
Come and walk among us.
Be our Savior and our Friend.
O come, O come, Immanuel.
Come to bring us your peace.
