O God, the strength of all those who put their trust in you,  mercifully accept our prayers and, because through the weakness of our mortal nature we can do no good thing without you, grant us the help of your grace, that in the keeping of your  commandments we may please you both in will and deed; through Jesus Christ your Son our Lord, who is alive and reigns with  you, in the unity of the Holy Spirit, one God, now and for ever. Amen
