"Nor did He stand in need of our service when He ordered us to follow Him; but He thus bestowed salvation upon ourselves."

"Not needing our service, but, bestowing salvation upon us [(nobis ipsis)], He commanded that we follow Him."

"Neque nostro ministerio indigens, iussit ut eum sequeremur, sed nobis ipsis attribuens salutem."
