Collect for the First Sunday of Advent

Almighty God, give us grace to cast away the works of darkness and to put on the armour of light, now in the time of this mortal life, in which your Son Jesus Christ came to us in great humility; that on the last day, when he shall come again in his glorious majesty to judge the living and the dead, we may rise to the life immortal; through him who is alive and reigns with you, in the unity of the Holy Spirit, one God, now and for ever.
