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.
Berean Study Bible (BSB) - 1 Corinthians 7:22 >For he who was a slave when he was called by the Lord is the Lord’s freedman. Conversely, he who was a free man when he was called is Christ’s slave.
