O God, the strength of all who put their trust in you: Mercifully accept our prayers; and because in our weakness we can do nothing good without you, give us the help of your grace, that in keeping your commandments we may please you both in will and deed; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
