Romans 15:16

"That I should be the minister of Jesus Christ to the Gentiles, ministering the Gospel of God." For after his abundant proof of his statements, he draws his discourse to a more lofty tone, not speaking of mere service, as in the beginning, but of service and priestly ministering. For to me this is a priesthood, this preaching and declaring. This is the sacrifice I bring. Now no one will find fault with a priest, for being anxious to offer the sacrifice without blemish. And he says this at once to elevate their thoughts, and show them that they are a sacrifice, and in apology for his own part in the matter, because he was appointed to this office. For my knife, he says, is the Gospel, the word of the preaching. And the cause is not that I may be glorified, not that I may appear conspicuous, but that the "offering up of the Gentiles may be acceptable, being sanctified by the Holy Ghost." That is, that the souls of those that are taught by me, may be accepted. For it was not so much to honor me, that God led me to this pitch, as out of a concern for you. And how are they to become acceptable? In the Holy Spirit. For there is need not only of faith, but also of a spiritual way of life, that we may keep the Spirit that was given once for all. For it is not wood and fire, nor altar and knife, but the Spirit that is all in us. For this cause, I take all means to prevent that Fire from being extinguished, as I have been also enjoined to do. Why then do you speak to those that need it not? This is just the reason why I do not teach you, but put you in mind, he replies. As the priest stands by stirring up the fire, so I do, rousing up your ready-mindedness. And observe, he does not say, "that the offering up of" you "may be" etc. but "of the Gentiles." But when he says of the Gentiles, he means the whole world, the land, and the whole sea, to take down their haughtiness, that they might not disdain to have him for a teacher, who was putting himself forth to the very end of the world. As he said in the beginning, "as among the other Gentiles also, I am a debtor to Greeks, and also to barbarians, to wise, and to foolish."
