Romans 15:13 (KJV)

Now I say that Jesus Christ was a minister of the circumcision for the truth of God, to confirm the promises made unto the fathers:

And that the Gentiles might glorify God for his mercy; as it is written, For this cause I will confess to thee among the Gentiles, and sing unto thy name.

And again he saith, Rejoice, ye Gentiles, with his people.

And again, Praise the Lord, all ye Gentiles; and laud him, all ye people.

That I should be the minister of Jesus Christ to the Gentiles, ministering the gospel of God, that the offering up of the Gentiles might be acceptable, being sanctified by the Holy Ghost.

I have therefore whereof I may glory through Jesus Christ in those things which pertain to God.

For I will not dare to speak of any of those things which Christ hath not wrought by me, to make the Gentiles obedient, by word and deed,
