1 Thessalonians 3:4

"That no man be moved by these afflictions; for yourselves know that hereunto we are appointed. For verily, when we were with you, we told you beforehand that we are to suffer affliction; even as it came to pass, and ye know." What then does he say here? Because the temptations of the teachers trouble their disciples, and he had then fallen into many temptations, as also he himself says, that "Satan hindered us," always saying this; "both once," he says, "and again I would have come to you," and was not able, which was a proof of great violence. And it was reasonable that this should trouble them, for they are not so much troubled at their own temptations, as at those of their teachers; as neither is the soldier so much troubled at his own trials, as when he sees his general wounded. "To establish you," he says; not that they were at all deficient in faith, nor that they required to learn anything. Ye ought not, he says, to be troubled, for nothing strange, nothing contrary to expectation is happening; which was sufficient to raise them up. For do you see that on this account also Christ foretold to His disciples? For hear Him saying, "Now I have told you before it came to pass, that when it is come to pass ye may believe." (John xiv. 29) For greatly indeed, greatly does it tend to the comfort of others, to have heard from their teachers what is to happen. For as he that is sick, if he hear from his physician that this or that is taking place, is not much troubled; but if anything happen unexpectedly, as if he too were at a loss, and the disorder was beyond his art, he is afflicted and troubled; so also is it here. Which Paul fore-knowing, foretold to them, "we are about to be afflicted," "as it came to pass, and ye know." He not only says that this came to pass, but that he foretold many things, and they happened. "Hereunto we are appointed." So that not only ye ought not to be troubled and disturbed about the past, but not even about the future, if any such thing should happen, "for hereunto we are appointed." Let us hear, who have ears to hear. The Christian is appointed hereunto. For concerning all the faithful is this said, "Hereunto we are appointed." And we, as if we were appointed for ease, think it strange if we suffer anything; and yet what reason have we for thinking anything strange? For no season of affliction or temptation has overtaken us, but what is common to man.
