1 Corinthians 7:22

For he who was called in the Lord as a bondservant is a freedman of the Lord . Likewise he who was free when called is a bondservant of Christ .

For the one who was a slave when called to faith in the Lord is the Lord`s freed person; similarly, the one who was free when called is Christ`s slave.

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.
