Thematic Bible: Who is a minister of God

So that he who resisteth the power, resisteth the ordinance of God: and they that resist shall receive condemnation. For rulers are not a terror to good works, but to the evil.

And such confidence have we through Christ towards God: not that we can of ourselves reckon upon any thing as from ourselves, but our sufficiency is from God. Who hath also fitted us to be ministers of the new covenant, not of the letter, but of the Spirit: for the letter killeth, but the Spirit giveth life.
