"bought with a price" - 1 Corinthians 6:20
"For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s." (1 Corinthians 6:20)
In "Biblical Perspective", Dr. Gordon Snider writes:

Ye are bought with a price. Your body should have a “Sold” sign on it! The purchase price is the blood of Christ which “cleanses from guilt,” “releases from bondage,” and “abolishes the enmity” that sin created between man and God (The Essentials of Life, W. H. Griffith Thomas). Therefore glorify God in your body. This might be translated “with your body,” but “in” is the more literal reading of the Greek text. Since the property in which you live belongs to God, live in such a way as to bring Him glory. Don’t trash the place where you live with immorality which is not becoming to the owner of the house.

Discussion: Since we have been bought by the blood of Christ, how then should we live?
