The word redeem means “to buy out.” The term was used specifically in reference to the purchase of a slave’s freedom. The application of this term to Christ’s death on the cross is quite telling. If we are “redeemed,” then our prior condition was one of slavery. God has purchased our freedom, and we are no longer in bondage to sin or to the Old Testament law. This metaphorical use of “redemption” is the teaching of Galatians 3:13 and 4:5.
