Be afflicted. Paul’s afflictions, together with the divine comfort that came to him in his affliction, were all on behalf of those who were won by him to Christ. More than that, such afflictions provided an opportunity for patient endurance, which new converts might emulate. Also, Paul’s afflictions qualified him to give consolation and counsel to others who might go through similar experiences.
Which is effectual. Important textual evidence may be cited (cf. p. 10) for reading this long middle clause of the sentence at the close of the verse, thus applying it to the comfort Paul experienced as well as to his afflictions. The afflictions and consolations experienced by church leaders often prove to be of great value to the people they serve. The courageous, patient example of the former encourages the latter (see Phil. 1:13, 14). The patient endurance of affliction ever tends to promote salvation and sanctification (Rom. 5:3-5; 8:28).
Comforted. Gr. parakaled (see on Matt. 5:4; cf. 2 Cor. 1:3, 4).
