1 Corinthians 7:21-23; 1 Corinthians 12:13
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.
Ye are bought with a price; be not ye the servants of men.
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.
