18 Now, whosoever of the faithful have piously pondered on all these things must need be inflamed with the charity of Christ in His agony and make a more vehement endeavor to expiate their own faults and those of others, to repair the honor of Christ, and to promote the eternal salvation of souls. And indeed that saying of the Apostle: "Where sin abounded, grace did more abound" ( Romans v, 20) may be used in a manner to describe this present age; for while the wickedness of men has been greatly increased, at the same time, by the inspiration of the Holy Ghost, a marvelous increase has been made in the number of the faithful of both sexes who with eager mind endeavor to make satisfaction for the many injuries offered to the Divine Heart, nay more they do not hesitate to offer themselves to Christ as victims. For indeed if any one will lovingly dwell on those things of which we have been speaking, and will have them deeply fixed in his mind, it cannot be but he will shrink with horror from all sin as from the greatest evil, and more than this he will yield himself wholly to the will of God, and will strive to repair the injured honor of the Divine Majesty, as well by constantly praying, as by voluntary mortifications, by patiently bearing the afflictions that befall him, and lastly by spending his whole life in this exercise of expiation.
