1 Corinthians 7
21 Ref If you were a servant when you became a Christian, let it not be a grief to you; but if you have a chance to become free, make use of it.
22 Ref For he who was a servant when he became a Christian is the Lord's free man; and he who was free when he became a Christian is the Lord's servant.
23 Ref It is the Lord who has made payment for you: be not servants of men.
