'Servant of Christ' in the Bible

Paul, a servant of Christ Jesus, called to be an apostle, set apart for the Good News of God,

that I should be a servant of Christ Jesus to the Gentiles, serving as a priest the Good News of God, that the offering up of the Gentiles might be made acceptable, sanctified by the Holy Spirit.

For am I now seeking the favor of men, or of God? Or am I striving to please men? For if I were still pleasing men, I would not be a servant of Christ.

even as you learned of Epaphras our beloved fellow servant, who is a faithful servant of Christ on your behalf,

Epaphras, who is one of you, a servant of Christ, salutes you, always striving for you in his prayers, that you may stand perfect and fully assured in all the will of God.

If you instruct the brothers of these things, you will be a good servant of Christ Jesus, nourished in the words of the faith, and of the good doctrine which you have followed.
