The collect for today, the Fourth Sunday in Advent, from The Book of Common Prayer (Canadian, 1962):
RAISE up, we beseech thee, O Lord, thy power, and come among us, and with great might succour us; that whereas, through our sins and wickedness, we are sore let and hindered in running the race that is set before us, thy bountiful grace and mercy may speedily help and deliver us; who with the Father and the Holy Spirit livest and reignest, one God, world without end. Amen.
