Commentaries
1:24-29 Both the sufferings of the Head and of the members are called the sufferings of Christ, and make up, as it were, one body of sufferings. But He suffered for the redemption of the church; we suffer on other accounts; for we do but slightly taste that cup of afflictions of which Christ first drank deeply. A Christian may be said to fill up that which remains of the sufferings of Christ, when he takes up his cross, and after the pattern of Christ, bears patiently the afflictions God allots to him. Let us be thankful that God has made known to us mysteries hidden from ages and generations, and has showed the riches of his glory among us. As Christ is preached among us, let us seriously inquire, whether he dwells and reigns in us; for this alone can warrant our assured hope of his glory. We must be faithful to death, through all trials, that we may receive the crown of life, and obtain the end of our faith, the salvation of our souls.
29. Whereunto—namely, "to present every man perfect in Christ."
I also labour—rather, "I labor also." I not only "proclaim" (English Version, "preach") Christ, but I labor also.
striving—in "conflict" (Col 2:1) of spirit (compare Ro 8:26). The same Greek word is used of Epaphras (Col 4:12), "laboring fervently for you in prayers": literally, "agonizing," "striving as in the agony of a contest." So Jesus in Gethsemane when praying (Lu 22:44): so "strive" (the same Greek word, "agonize"), Lu 13:24. So Jacob "wrestled" in prayer (Ge 32:24-29). Compare "contention," Greek, "agony," or "striving earnestness," 1Th 2:2.
according to his working—Paul avows that he has power to "strive" in spirit for his converts, so far only as Christ works in him and by him (Eph 3:20; Php 4:13).
mightily—literally, "in power."
