Thematic Bible: Who is a minister of God

Let every soul be subject to the higher authorities. For there is no authority but from God: the authorities that are, have been appointed by God. Therefore, he that resists the authority, resists the appointment of God; and those who resist shall receive to themselves condemnation. For rulers are not a terror to works that are good, but to those which are evil. Will you, then, not be afraid of the authority? Do that which is good, and you shall receive praise from the same. read more.
For he is the minister of God to you for that which is good. But if you do what is evil, be afraid; for he bears not the sword in vain. For he is the minister of God to inflict punishment on him that does evil. Wherefore, it is necessary to be subject, not only because of punishment, but also for conscience sake. On this very account, too, pay tribute also: for they are the public servants of God, attending continually to this very thing.

Do we begin again to commend ourselves? or do we need, as some do, letters of commendation to you, or letters of commendation from you? You are our letter, written in our hearts, known and read by all men; you are well known to be a letter of Christ, written by us as his ministers, not with ink, but with the Spirit of the living God, not in tables of stone, but in fleshy tables of the heart. read more.
Now, confidence such as this we have, through the Christ, toward God; not that we are able, of ourselves, to devise any thing, as from ourselves; but our ability is from God, who has made us able ministers of the new covenant, not of letter, but. of spirit: for the letter kills, but the spirit makes alive.
