Collect for the Fourth Sunday of Advent

Purify our conscience, Almighty God, by your daily visitation, that your Son Jesus Christ, at his coming, may find in us a mansion prepared for himself; who lives and reigns with you, in the unity of the Holy Spirit, one God, now and for ever. Amen.

A collect is a short liturgical prayer, variable according to the day, the season of the church year, and the occasion. Collects for each Sunday are assigned according to the church year and are all listed in the Book of Common Prayer.
