From Starck's

O my God, increase in me faith, holiness, and obedience, that with each day I may become more pious, devout, and God-fearing, ever growing in conformity to the image of my Savior. Keep me in this grace to my blessed end, that I may live as a true and pious Christian, and also die in peace at Your appointed time. -- Prayer for the preservation and increase of faith (p. 139)
