In this passage the Apostle returns from what is virtually, if not formally, a digression, to the narrative which begins in chap. i. 8 f., and is continued in i. 15 f. At the same time he makes a transition to a new subject, really though not very explicitly connected with what goes before--namely, his independent and divinely granted authority as an apostle. In the last verses of chap, ii., and in chap. iii. 1-4, this is treated generally, but with reference in particular to the success of his ministry. He then goes on to contrast the older and the Christian dispensation, and the character of their respective ministries, and terminates the section with a noble statement of the spirit and principles with which he fulfilled his apostolic calling (chap. iv. 1-6). Before leaving Ephesus, Paul had apparently made an appointment to meet Titus, on his return from Corinth, at Troas. He went thither himself to preach the Gospel, and found an excellent opportunity for doing so; but the non-arrival of his brother kept him in such a state of unrest[19] that he was unable to make that use of it which he would otherwise have done. This seems a singular confession, but there is no reason to suppose that it was made with a bad conscience. Paul was probably grieved that he had not the heart to go in at the door which had been opened to him in the Lord, but he did not feel guilty. It was not selfishness which made him turn away, but the anxiety of a true pastor about other souls which God had committed to his care. "I had no relief _for my spirit_," he says; and the spirit, in his language, even though it be a constituent of man's nature, is that in him which is akin to the divine, and receptive of it. That very element in the Apostle, in virtue of which he could act for God at all, was already preoccupied, and though the people were there, ready to be evangelised, it was beyond his power to evangelise them. His spirit was absorbed and possessed by hopes and fears and prayers for the Corinthians; and as the human spirit, even when in contact with the divine, is finite, and only capable of so much and no more, he was obliged to let slip an occasion which he would otherwise have gladly seized. He probably felt with all missionaries that it is as important to secure as to win converts; and if the Corinthians were capable of reflection, they might reflect with shame on the loss which their sin had entailed on the people of Troas. The disorders of their wilful community had engrossed the Apostle's spirit, and robbed their fellow-men across the sea of an apostolic ministry. They could not but feel how genuine was the Apostle's love, when he had made such a sacrifice to it; but such a sacrifice ought never to have been required.
