Acts 26:18

That they may be converted from the darkness of error to the light of the gospel, and from the power of Satan to the liberty of the children of God.

6. He preached no doctrine but what agreed with the scriptures of the Old Testament: He witnessed both to small and great, to young and old, rich and poor, learned and unlearned, obscure and illustrious, all being concerned in it. It was an evidence of the condescending grace of the gospel that it was witnessed to the meanest, and the poor were welcome to the knowledge of it; and of the incontestable truth and power of it that it was neither afraid nor ashamed to show itself to the greatest. The enemies of Paul objected against him that he preached something more than that men should repent, and turn to God, and do works meet for repentance. These indeed were but what the prophets of the old Testament had preached; but, besides these, he had preached Christ, and his death, and his resurrection, and this was what they quarrelled with him for, as appears by ch. 25 19, that he affirmed Jesus to be alive: "And so I did," says Paul, "and so I do, but therein also I say no other than that which Moses and the prophets said should come; and what greater honour can be done to them than to show that what they foretold is accomplished, and in the appointed season too—that what they said should come is come, and at the time they prefixed?" Three things they prophesied, and Paul preached:—(1.) That Christ should suffer, that the Messiah should be a sufferer—pathetos; not only a man, and capable of suffering, but that, as Messiah, he should be appointed to sufferings; that his ignominious death should be not only consistent with, but pursuant of, his undertaking. The cross of Christ was a stumbling-block to the Jews, and Paul's preaching it was the great thing that exasperated them; but Paul stands to it that, in preaching that, he preached the fulfilling of the Old-Testament predictions, and therefore they ought not only not to be offended at what he preached, but to embrace it, and subscribe to it. (2.) That he should be the first that should rise from the dead; not the first in time, but the first in influence—that he should be the chief of the resurrection, the head, or principal one, protos ex anastaseos, in the same sense that he is called the first-begotten from the dead (Rev 1 5), and the first-born from the dead, Col 1 18. He opened the womb of the grave, as the first-born are said to do, and made way for our resurrection; and he is said to be the first-fruits of those that slept (1 Cor 15 20), for he sanctified the harvest. He was the first that rose from the dead to die no more; and, to show that the resurrection of all believers is in virtue of his, just when he arose many dead bodies of saints arose, and went into the holy city, Matt 27 52, 53. (3.) That he should show light unto the people, and to the Gentiles, to the people of the Jews in the first place, for he was to be the glory of his people Israel. To them he showed light by himself, and then to the Gentiles by the ministry of his apostles, for he was to be a light to enlighten those who sat in darkness. In this Paul refers to his commission (v. 18), To turn them from darkness to light. He rose from the dead on purpose that he might show light to the people, that he might give a convincing proof of the truth of his doctrine, and might send it with so much the greater power, both among Jews and Gentiles. This also was foretold by the Old-Testament prophets, that the Gentiles should be brought to the knowledge of God by the Messiah; and what was there in all this that the Jews could justly be displeased at?

Verses 12-23 Paul was made a Christian by Divine power; by a revelation of Christ both to him and in him; when in the full career of his sin. He was made a minister by Divine authority: the same Jesus who appeared to him in that glorious light, ordered him to preach the gospel to the Gentiles. A world that sits in darkness must be enlightened; those must be brought to know the things that belong to their everlasting peace, who are yet ignorant of them. A world that lies in wickedness must be sanctified and reformed; it is not enough for them to have their eyes opened, they must have their hearts renewed; not enough to be turned from darkness to light, but they must be turned from the power of Satan unto God. All who are turned from sin to God, are not only pardoned, but have a grant of a rich inheritance. The forgiveness of sins makes way for this. None can be happy who are not holy; and to be saints in heaven we must be first saints on earth. We are made holy, and saved by faith in Christ; by which we rely upon Christ as the Lord our Righteousness, and give up ourselves to him as the Lord our Ruler; by this we receive the remission of sins, the gift of the Holy Ghost, and eternal life. The cross of Christ was a stumbling-block to the Jews, and they were in a rage at Paul's preaching the fulfilling of the Old Testament predictions. Christ should be the first that should rise from the dead; the Head or principal One. Also, it was foretold by the prophets, that the Gentiles should be brought to the knowledge of God by the Messiah; and what in this could the Jews justly be displeased at? Thus the true convert can give a reason of his hope, and a good account of the change manifest in him. Yet for going about and calling on men thus to repent and to be converted, vast…
