2 Timothy 4:20

7. Nevertheless, we will not frame our answer from these things only, but will also say something yet further. For God, foreseeing these things of old, destroyed, in His wisdom, this plea of theirs. On this account He made the world not only wonderful and vast, but also corruptible and perishable; and placed therein many evidences of its weakness; and what He did with respect to the Apostles, He did with respect to the whole world. What then did He with respect to the Apostles? Since they used to perform many great and astonishing signs and wonders, He suffered them constantly to be scourged, to be expelled, to inhabit the dungeon, to encounter bodily infirmities, to be in continual tribulations, lest the greatness of their miracles should make them to be accounted as gods amongst mankind. …

Ver. 20 . “Erastus abode at Corinth: but Trophimus have I left at Miletum sick.” This Trophimus and Tychicus, we know from the book of the Acts, sailed away with him from Judea, and were everywhere his companions, perhaps as being more zealous than the rest. “Trophimus I have left at Miletum sick.” Why then didst thou not heal him, instead of leaving him? The Apostles could not do everything, or they did not dispense miraculous gifts upon all occasions, lest more should be ascribed to them than was right. The same thing is observable of those blessed and righteous men, who were before them, as in the case of Moses, whose voice was weak. Why was not this defect removed? Nay, he was often afflicted with grief and dejection, and he was not admitted into the Land of Promise.

Why then does he put Luke last? And yet he elsewhere says, “Only Luke is with me” ( 2 Tim. iv. 11 .), and “Demas,” he says, was one of those who “forsook him, having loved the present world.” ( 2 Tim. iv. 10 .) All these things, although they are mentioned elsewhere, yet nevertheless ought not to be passed over here without enquiry, nor ought we merely to hear them as things of course. But how comes he to say that he who forsook him salutes them? For “Erastus,” he says, “abode at Corinth.” ( 2 Tim. iv. 20 .) He adds Epaphras, both as known to them, and being of their country. And Mark, as being himself also an admirable man. Why then does he number Demas with these? Perhaps it was after this that he became more remiss, when he saw the dangers multiplied. But Luke being last became first. …
