'Servants' in the Bible

who also made us adequate as servants of a new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life.

For this reason, because we have been made servants of this new order, through the mercy given to us, we are strong:

For we preach not ourselves, but Christ Jesus the Lord; and ourselves your servants for Jesus' sake.

Instead, in every way we demonstrate that we are God's servants by tremendous endurance in the midst of difficulties, hardships, and calamities;

Seriously requesting us that they might have a part in this grace of being servants to the needs of the saints:

So it is no great thing if his servants also disguise themselves as servants of righteousness. Their destiny will be according to their works.

You put up with a man if he makes servants of you, if he makes profit out of you, if he makes you prisoners, if he puts himself in a high place, if he gives you blows on the face.

Are they servants of Christ?I’m talking like a madman—I’m a better one:with far more labors,many more imprisonments,far worse beatings, near death many times.
