Heart Righteousness
Heart righteousness = God cares about the inner life, not only outward acts - anger is murder in the heart; lust is adultery in the heart (Matthew 5:21-30).
Jesus didn't lower the law; he exposed its depth. “You have heard… but I say” moves righteousness from courtroom compliance to motive and imagination. Under Free Grace, this isn't a new merit ladder - it's the standard the Spirit applies to a life already saved, starting where only God sees.
Extends Judge Not. Contradicts Let Your Light Shine when I polish the outside while nursing anger inside.
