Thematic Bible: Who is a minister of God

Let every person be loyally subject to the governing (civil) authorities. For there is no authority except from God [by His permission, His sanction], and those that exist do so by God's appointment. Therefore he who resists and sets himself up against the authorities resists what God has appointed and arranged [in divine order]. And those who resist will bring down judgment upon themselves [receiving the penalty due them]. For civil authorities are not a terror to [people of] good conduct, but to [those of] bad behavior. Would you have no dread of him who is in authority? Then do what is right and you will receive his approval and commendation. read more.
For he is God's servant for your good. But if you do wrong, [you should dread him and] be afraid, for he does not bear and wear the sword for nothing. He is God's servant to execute His wrath (punishment, vengeance) on the wrongdoer. Therefore one must be subject, not only to avoid God's wrath and escape punishment, but also as a matter of principle and for the sake of conscience. For this same reason you pay taxes, for [the civil authorities] are official servants under God, devoting themselves to attending to this very service.

Are we starting to commend ourselves again? Or we do not, like some [false teachers], need written credentials or letters of recommendation to you or from you, [do we]? [No] you yourselves are our letter of recommendation (our credentials), written in your hearts, to be known (perceived, recognized) and read by everybody. You show and make obvious that you are a letter from Christ delivered by us, not written with ink but with [the] Spirit of [the] living God, not on tablets of stone but on tablets of human hearts. read more.
Such is the reliance and confidence that we have through Christ toward and with reference to God. Not that we are fit (qualified and sufficient in ability) of ourselves to form personal judgments or to claim or count anything as coming from us, but our power and ability and sufficiency are from God. [It is He] Who has qualified us [making us to be fit and worthy and sufficient] as ministers and dispensers of a new covenant [of salvation through Christ], not [ministers] of the letter (of legally written code) but of the Spirit; for the code [of the Law] kills, but the [Holy] Spirit makes alive.
