Collect for the 23rd Sunday after Pentecost

O God, whose blessed Son came into the world that he might destroy the works of the devil and make us children of God and heirs of eternal life: Grant that, having this hope, we may purify ourselves as he is pure; that, when he comes again with power and great glory, we may be made like him in his eternal and glorious kingdom; where he lives and reigns with you and the Holy Spirit, one God, for ever and 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.
