'Free' in the Bible

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.

Am I not an apostle? am I not free? have I not seen Jesus Christ our Lord? are not ye my work in the Lord?

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

For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
