What does the word Belial mean in 2 Corinthians 6:15?
In 2 Corinthians 6:15, Belial means something worthless. It is not a reference to a pagan god, but denotes that which has no value. Paul contrasts Christ, who is the epitome of goodness, grace, righteousness, and majesty, with Belial, representing utter worthlessness.
Les explains that the word Belial is used several times in the Old Testament. He once thought it was a reference to some pagan god, but it is not; it means something worthless. He then asks us to analyze this: if Christ is the epitome of everything great—goodness, grace, righteousness, and majesty—putting Him alongside something worthless is ridiculous, just as ridiculous as putting a little donkey beside an ox. This illustrates the absolute incompatibility between Christ and Belial. In the same passage, Les notes that a believer and an infidel are total opposites and cannot pull together, and that the temple of God has no agreement with idols.
And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
