39 The things that I have here set forth will seem hard to her who loves not Christ. But one who has come to regard all the splendor of the world as off-scourings, and to hold all things under the sun as vain, that he may win Christ; one who has died with his Lord and risen again, and has crucified the flesh with its affections and lusts; he will boldly cry out: “Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?” and again: “I am persuaded that neither death nor life, nor angels, nor principalities nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature shall be able to separate us from the love of God which is in Christ Jesus, our Lord.”
For our salvation the Son of God is made the Son of Man. Nine months He awaits His birth in the womb, undergoes the most revolting conditions, and comes forth covered with blood, to be swathed in rags and covered with caresses. He who shuts up the world in His fist is contained in the narrow limits of a manger. I say nothing of the thirty years during which he lives in obscurity, satisfied with the poverty of his parents. When He is scourged He holds His peace; when He is crucified, He prays for His crucifiers. “What shall I render unto the Lord for all His benefits towards me? I will take the cup of salvation and call upon the name of the Lord. Precious in the sight of the Lord is the death of His saints.” The only fitting return that we can make to Him is to give blood for blood; and, as we are redeemed by the blood of Christ, gladly to lay down our lives for our Redeemer. What saint has ever won his crown without first contending for it? Righteous Abel is murdered. Abraham is in danger of losing his wife. And, as I must not enlarge my book unduly, seek for yourself: you will find that all holy men have suffered adversity. Solomon alone lived in luxury and perhaps it was for this reason that he fell. For “whom the Lord loves, He chastens, and scourges every son whom He receives.” Which is best— for a short time to do battle, to carry stakes for the palisades, to bear arms, to faint under heavy bucklers, that ever afterwards we may rejoice as victors? Or to become slaves forever, just because we cannot endure for a single hour?
