Roma 11:13

11:13 Now I am speaking to you Gentiles. Seeing that I am an apostle to the Gentiles, I magnify my ministry,

Roma 15:15-16

15:15 But I have written more boldly to you on some points so as to remind you, because of the grace given to me by God 15:16 to be a minister of Christ Jesus to the Gentiles. I serve ¹  the gospel of God ²  like a priest, so that the Gentiles may become an acceptable offering, ³  sanctified by the Holy Spirit.

[15:16]  ¹ tn Grk “serving.” This is a continuation of the previous sentence in the Greek text, but in keeping with contemporary English style, a new sentence was started here in the translation.

[15:16]  ² tn The genitive in the phrase τὸ εὐαγγέλιον τοῦ θεοῦ (to euangelion tou qeou, “the gospel of God”) could be translated as either a subjective genitive (“the gospel which God brings”) or an objective genitive (“the gospel about God”). Either is grammatically possible. This is possibly an instance of a plenary genitive (see ExSyn 119-21; M. Zerwick, Biblical Greek, §§36-39). If so, an interplay between the two concepts is intended: The gospel which God brings is in fact the gospel about himself.

[15:16]  ³ tn Grk “so that the offering of the Gentiles may become acceptable.” This could be understood to refer to an offering belonging to the Gentiles (a possessive genitive) or made by the Gentiles (subjective genitive), but more likely the phrase should be understood as an appositive genitive, with the Gentiles themselves consisting of the offering (so J. D. G. Dunn, Romans [WBC 38], 2:860). The latter view is reflected in the translation “so that the Gentiles may become an acceptable offering.”
