Commentary

KJV Study Commentary
Thou believest that there is one God; thou doest well: the devils also believe, and tremble. Believing God is one (heis estin ho Theos, εἷς ἐστιν ὁ Θεός) is orthodox monotheism, but even demons (daimonia, δαιμόνια) believe and shudder (phrissousin, φρίσσουσιν). Intellectual assent without obedience aligns us with demonic faith—accurate but unredeemed.

Reformed theology distinguishes notitia and assensus from fiducia: knowledge and assent must be joined with trusting reliance. Mere doctrinal correctness without transformation is demonic-level belief.

Historical & Cultural Context

Jewish Shema confession (Deuteronomy 6:4) was recited daily. James warns that reciting truth without embodying love is worthless. Demons have sound theology yet oppose God. Paul similarly warns in Romans 2 that possessing the law while disobeying it brings judgment.

Reflection Questions

  2. How can you ensure doctrine fuels love, not pride?
