For so hath the Lord commanded us, saying, I have set thee to be a light of the Gentiles, that thou shouldest be for salvation unto the ends of the earth. For so the Lord commanded us - The apostles could quote a pertinent scripture for every thing they did; because the outlines of the whole Gospel dispensation are founded in the law and the prophets; and they were now building the Church of God according to the pattern shown them in the Mount. In the things of God, no man nor minister should go farther than he can say, Thus it is written, and thus it behoves me to do; and let him see that his quotations are fairly made, and not a detached passage or member of a sentence produced, because it seems to look like the system he wishes to establish.
I have set thee to be a light of the Gentiles - This quotation is from Isaiah 49:6, and was most fully in point. The Jews could not resist the testimony of their own prophet; and the Gentiles rejoiced to find that the offers of salvation were to be made so specifically to them.
For salvation unto the ends of the earth - The very name of the Messiah, viz Jesus, announced the design and end of his mission. He is the Savior, and is to be proclaimed as such to the ends of the earth; to all mankind; to every nation, and people, and tongue; and, wherever the Gospel is preached, there is a free, full, and sincere offer of salvation to every soul that hears it. And the offer is proof sufficient, in itself, that there is a power to receive its blessings given to those to whom the offer is made; as it would be of no use to offer them a salvation which it was designed they either should not or could not receive. A son of Satan might be capable of such dissimulation and bad faith; but the holy God cannot.
