The next three verses carry us back to chap. ii. 12 ff., and resume the story which was interrupted there at ver. 14. The sudden thanksgiving of that passage--so eager and impetuous that it left the writer no time to tell what he was thankful for--is explained here. Titus, whom he had expected to see in Troas, arrived at length, probably at Philippi, and brought with him the most cheering news. Paul was sadly in need of it. His flesh had no rest: the use of the perfect (ἔσχηκεν) almost conveys the feeling that he began to write whenever he got the news, so that up to this moment the strain had continued. The fights without were probably assaults upon himself, or the Churches, of the nature of persecution; the fears within, his anxieties about the state of morals, or of Gospel truth, in the Christian communities. Outworn and depressed, burdened both in body and mind (cf. the expressions in ii. 13 and vii. 5), he was suddenly lifted on high by the arrival and the news of Titus. Here again, as in ii. 14, he ascribes all to God. It was He whose very nature it is to comfort the lowly who so graciously comforted him. Titus apparently had gone himself with a sad and apprehensive heart to Corinth; he had been away longer than he had anticipated, and in the interval St. Paul's anxiety had risen to anguish; but in Corinth his reception had been unexpectedly favourable, and when he returned he was able to console his master with a consolation which had already gladdened his own heart. Paul was not only comforted, his sorrow was turned into joy, as he listened to Titus telling of the longing of the Corinthians to see him, of their mourning over the pain they had given him by their tolerance for such irregularities as that of the incestuous man or the unknown insulter of the Apostle, and of their eagerness to satisfy him and maintain his authority. The word "your" (ὑμῶν) in ver. 7 has a certain emphasis which suggests a contrast. Before Titus went to Corinth, it was Paul who had been anxious to see _them_, who had mourned over their immoral laxity, who had been passionately interested in vindicating the character of the Church he had founded; now it is _they_ who are full of longing to see _him_, of grief, and of moral earnestness; and it is this which explains his joy. The conflict between the powers of good in one great and passionate soul, and the powers of evil in a lax and fickle community, has ended in favour of the good; Paul's vehemence has prevailed against Corinthian indifference, and made it vehement also in all good affections, and he rejoices now in the joy of his Lord.
