Romans 15:16
15:16 to be a minister of Christ Jesus to the Gentiles. I serve the gospel of God like a priest, so that the Gentiles may become an acceptable offering, sanctified by the Holy Spirit.
Romans 15:27
15:27 For they were pleased to do this, and indeed they are indebted to the Jerusalem saints. For if the Gentiles have shared in their spiritual things, they are obligated also to minister to them in material things.
