18:24-28 Apollos taught in the gospel of Christ, as far as John's ministry would carry him, and no further. We cannot but think he had heard of Christ's death and resurrection, but he was not informed as to the mystery of them. Though he had not the miraculous gifts of the Spirit, as the apostles, he made use of the gifts he had. The dispensation of the Spirit, whatever the measure of it may be, is given to every man to profit withal. He was a lively, affectionate preacher; fervent in spirit. He was full of zeal for the glory of God and the salvation of precious souls. Here was a complete man of God, thoroughly furnished for his work. Aquila and Priscilla encouraged his ministry, by attendance upon it. They did not despise Apollos themselves, or undervalue him to others; but considered the disadvantages he had laboured under. And having themselves got knowledge in the truths of the gospel by their long intercourse with Paul, they told what they knew to him. Young scholars may gain a great deal by converse with old Christians. Those who do believe through grace, yet still need help. As long as they are in this world, there are remainders of unbelief, and something lacking in their faith to be perfected, and the work of faith to be fulfilled. If the Jews were convinced that Jesus is Christ, even their own law would teach them to hear him. The business of ministers is to preach Christ. Not only to preach the truth, but to prove and defend it, with meekness, yet with power.
28. For he mightily convinced the Jews—The word is very strong: "stoutly bore them down in argument," "vigorously argued them down," and the tense in that he continued to do it, or that this was the characteristic of his ministry.
showing by the scriptures that Jesus was Christ—Rather, "that the Christ (or Messiah) was Jesus." This expression, when compared with Ac 18:25, seems to imply a richer testimony than with his partial knowledge he was at first able to bear; and the power with which he bore down all opposition in argument is that which made him such an acquisition to the brethren. Thus his ministry would be as good as another visitation to the Achaian churches by the apostle himself (see 1Co 3:6) and the more as, in so far as he was indebted for it to Priscilla and Aquila, it would have a decidedly Pauline cast.
