Romans 15:14-16

And I myself also am persuaded of you, my brethren, that ye yourselves are full of goodness, filled with all knowledge, able also to admonish one another. But I write the more boldly unto you in some measure, as putting you again in remembrance, because of the grace that was given me of God, that I should be a minister of Christ Jesus unto the Gentiles, ministering the gospel of God, that the offering up of the Gentiles might be made acceptable, being sanctified by the Holy Spirit.
