Commentary

KJV Study Commentary
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved—This is Christianity's most famous conversion formula. Homologeō (ὁμολογέω) means "confess, acknowledge publicly, declare allegiance." The confession's content: kyrion Iēsoun (κύριον Ἰησοῦν, "Jesus is Lord")—the earliest Christian creed (1 Cor 12:3; Phil 2:11). "Lord" (kyrios, κύριος) is the LXX translation of Yahweh; confessing Jesus as kyrios is a declaration of His deity and universal sovereignty.

Pisteuō en tē kardia (πιστεύω ἐν τῇ καρδίᾳ, "believe in the heart") is internal conviction, not mere intellectual assent (James 2:19). The heart (kardia, καρδία) in Hebraic thought is the volitional center—mind, will, affections united. The belief's content: that God hath raised him from the dead—the historical Resurrection as objective fact (1 Cor 15:14-17). Faith and confession are distinguished but inseparable—genuine heart-belief inevitably produces mouth-confession. Thou shalt be saved (sōthēsē, σωθήσῃ)—future passive, emphasizing God's saving action in response to faith-confession.

Historical & Cultural Context

"Jesus is Lord" was a politically dangerous confession in the Roman Empire, where Caesar claimed divine honors and "Lord" (kyrios) was an imperial title. Christians faced persecution for refusing to say "Caesar is lord" and burn incense to the emperor. This confession cost many their lives (Rev 2:13; martyrdom accounts). In Jewish contexts, calling Jesus "Lord" (Yahweh) was blasphemy to unbelievers but the heart of Christian orthodoxy. The early church's baptismal liturgies centered on this confession.

Reflection Questions

  1. Have you personally confessed Jesus as <em>kyrios</em>—absolute sovereign over your life, not just Savior from hell?
  2. How does belief in the historical Resurrection distinguish Christianity from all other religions and philosophies?
  3. What would it cost you to publicly confess Christ in your specific social, professional, and family context?
