1 Corinthians 7:21-23 NIV

[21] Were you a slave when you were called? Don’t let it trouble you—although if you can gain your freedom, do so. [22] 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. [23] You were bought at a price; do not become slaves of human beings.
