What is Christ the epitome of?
Christ is the epitome of everything great: goodness, grace, righteousness, and majesty. This contrasts with Belial, meaning something worthless, so putting Christ alongside worthlessness is ridiculous. The contrast highlights the impossibility of joining Him with anything worthless. He is the epitome of all that is excellent.
Les explains that Christ is the epitome of everything great—He is the epitome of goodness, grace, righteousness, and majesty. The word Belial means something worthless. Les asks how we could put Christ, who is the epitome of everything great, alongside something worthless; it is ridiculous, just as ridiculous as putting a little donkey beside an ox. This illustrates the total opposition between believers and unbelievers: a believer has no part with an infidel, and the temple of God has no agreement with idols. Our human physical body is the temple of the living God; God has said He will dwell in believers, walk in them, be their God, and they shall be His people. The unbeliever cannot claim that promise.
And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
