O God, who art Thyself the exceeding great Reward of all faithful souls, grant unto us to advance daily to the utmost of our power in godliness, so that we, seeking ever that which is more perfect, may happily attain unto Thine everlasting glory—Amen.

Roman Breviary.

O Almighty God, without whom we can do nothing, I firmly resolve before Thee to follow more closely the rule of Thy will; to amend my ways; to attend more diligently to the duties of my calling; to avoid all sin, and its occasions. Do Thou, who givest me the will, give me also the power to accomplish it. Grant what Thou commandest, and command what Thou wilt; that so I may live righteously in this present world, and in the world to come may praise Thee eternally—Amen.
