Romans 15:14-16

14Personally I am convinced about you, my brothers and sisters, that you yourselves are full of goodness, amply filled with all [spiritual] knowledge, and competent to admonish and counsel and instruct one another.

15Still, on some points I have written to you very boldly and without reservation to remind you [about them] again, because of the grace that was given to me from God,

16to be a minister of Christ Jesus to the Gentiles. I minister as a priest the gospel of God, in order that my offering of the Gentiles may become acceptable [to Him], sanctified [made holy and set apart for His purpose] by the Holy Spirit.
