15 Be sure, Brethren, that enemies have no power against the faithful, except so far as it profits them to be tempted and proved. Of this be sure, Brethren, let no one say ought against it. Cast all your care upon the Lord, throw yourselves wholly and entirely upon Him. He will not withdraw Himself that you should fall. He who created us, has given us security touching our very hairs. “Verily I say unto you, even the hairs of your head are all numbered.” Our hairs are numbered by God; how much more is our conduct known to Him to whom our hairs are thus known?
See then, how that God does not disregard our least things. For if He disregarded them, He would not create them. For He verily both created our hairs, and still takes count of them. But you will say, though they are preserved at present, perhaps they will perish. On this point also hear His word, “Verily I say unto you, there shall not an hair of your head perish.” Why are you afraid of man, O man, whose place is in the Bosom of God? Fall not out of His Bosom; whatsoever you shall suffer there, will avail to your salvation, not to your destruction.
Martyrs have endured the tearing of their limbs, and shall Christians fear the injuries of Christian times? He who would do you an injury now, can only do it in fear. He does not say openly, come to the idol-feast; he does not say openly, come to my altars, and banquet there. And if he should say so, and you were to refuse, let him make a complaint of it, let him bring it as an accusation and charge against you: “He would not come to my altars, he would not come to my temple, where I worship.”
Let him say this. He does not dare; but in his guile he contrives another attack. Make ready your hair; he is sharpening the razor; he is about to take off your superfluous things, to shave what you must soon leave behind you. Let him take off what shall endure, if he can. This powerful enemy, what has he taken away? What great thing has he taken away? That which a thief or housebreaker could take: in his utmost rage, he can but take what a robber can. Even if he should have license given him to the slaying of the very body, what does he take away, but what the robber can take?
I did him too much honour, when I said, “a robber.” For be the robber who and what he may, he is a man. He takes from you what a fever, or an adder, or a poisonous mushroom can take. Here lies the whole power of the rage of men, to do what a mushroom can! Men eat a poisonous mushroom, and they die. Lo! In what frail estate is the life of man; which sooner or later you must abandon; do not struggle then in such wise for it, as that you should be abandoned yourself.
