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.
