'Servant' in the Bible

Think of us as servants of the Messiah and as servant managers entrusted with God's secrets.

Now it is required of servant managers that each one should prove to be trustworthy.

Art thou called being a servant? care not for it: but if thou mayest be made free, use it rather.

For he that is called in the Lord, being a servant, is the Lord's freeman: likewise also he that is called, being free, is Christ's servant.

For though I be free from all men, yet have I made myself servant unto all, that I might gain the more.
