to which I was appointed a preacher and an apostle (I am telling the truth in Christ, not lying), a teacher of the Gentiles in faith and truth.
a teacher of the Gentiles in faith and verity; the Gospel of the uncircumcision, or which was to be preached to the uncircumcised Gentiles, was committed to this apostle; and his work and ministry lay among them, and therefore he is called the apostle of the Gentiles: and so he was in faith and verity; which may regard the subject matter of his teachings and ministry; it was the faith and truth of the Gospel, even the whole of it, the faith which was once delivered to the saints, and the truth as it is in Jesus; or else the character of the apostle, as a teacher, that he was a true and faithful one, who with all integrity and veracity, fully and faithfully preached the Gospel; and since he was appointed a teacher of it to the Gentiles, this is another argument why they, as well as the Jews, should be prayed for.
