Heart Belief and Mouth Confession: The Two-Part Gospel

Romans 10:10 reveals an essential harmony: "With the heart man believeth unto righteousness; and with the mouth confession is made unto salvation." The structure mirrors Deuteronomy 30:11-14, where Paul adapted the law to expose the gospel's logic.

First, evangelical faith differs radically from mere intellectual assent. Demons "believe and tremble" (James 2:19), yet possess no saving faith. True heart-belief (pistis) engages mind, affections, and will together. In Scripture, the heart reasons (Mark 2:6), meditates (Luke 3:15), and understands (Matthew 13:15). This faith centers upon Christ's resurrection—the demonstration of His Divinity (Romans 1:4). As the "outshining of the Father's glory, and the express image of His person" (Hebrews 1:3), Christ embodies Divine perfections. Faith in His resurrection necessarily implies belief in the entire mediatorial scheme.

This heart-faith yields dual righteousness: the forensic righteousness removing the objective barrier between sinners and the Father (Romans 3:22), and the subjective righteousness wrought within us as we imitate Christ's holy life (1 John 2:29; 3:7, 10). Justification by faith remains "the article of a standing or falling Church," yet the faith that justifies is "the faith which worketh by love" (Galatians 5:6).

Second, mouth-confession (homologia) publicly declares this inward conviction. The primitive baptismal confession parallels Mark 16:16. Confession transforms private conviction into covenant commitment before Adonai and community.
