In 1 Corinthians 7:21, 23, Paul had this to say about slavery. 21-Were you called while a slave? Do not worry about it; but if you are able also to become free, rather do that. 23-You were bought with a price; do not become slaves of men. Slavery is not God's doing but it's people who enslave people. God has patiently dealt with our sins and gradually He will establish righteousness throughout the entire earth.
