The collect for today, the 13th Sunday after Trinity, from the 1662 Book of Common Prayer:

Almighty and merciful God, of whose only gift it cometh that thy faithful people do unto thee true and laudable service; Grant, we beseech thee, that we may so faithfully serve thee in this life, that we fail not finally to attain thy heavenly promises; through the merits of Jesus Christ our Lord. Amen.
