Commentary

KJV Study Commentary
'Evil heart of unbelief' identifies the root problem—not intellectual doubt but moral rebellion against God. The warning 'departing from the living God' uses apostasia language, suggesting apostasy. Unbelief is not passive skepticism but active departure. The title 'living God' contrasts with dead idols and emphasizes covenant relationship.
