1 Corinthians 7:21-24

21Art thou called being a servant? care not for it: but if thou mayest be made free, use it rather. 22For 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.1 23Ye are bought with a price; be not ye the servants of men. 24Brethren, let every man, in the state in which he is called, continue in it with God.
