Romans 15:16-18

Young's Literal Translation

¹⁶ for my being a servant of Jesus Christ to the nations, acting as priest in the good news of God, that the offering up of the nations may become acceptable, sanctified by the Holy Spirit.

¹⁷ I have, then, a boasting in Christ Jesus, in the things pertaining to God,

¹⁸ for I will not dare to speak anything of the things that Christ did not work through me, to obedience of nations, by word and deed,
