Slave

“You were bought at a price; do not become slaves of men.”

I Corinthians 7:23 NKJV

The Lord Jesus have saved use, He has freed our chains. Let us no more be bound to men or worldly slavery. 

“You were bought with a price [purchased with a preciousness and paid for by Christ]; then do not yield yourselves up to become [in your own estimation] slaves to men [but consider yourselves slaves to Christ].”
