Purity of the Heart

In Matthew 5:27–30, Jesus exposes the inadequacy of outward morality by showing that the seventh commandment reaches beyond physical adultery into the heart. Deliberate, cultivated lust is adultery before God because the King judges not only actions but desires, intentions, and affections. Christ then commands radical repentance: anything that repeatedly becomes an avenue of temptation must be decisively removed. The eye and hand imagery is not a call to self-mutilation, but to serious mortification of sin. Jesus places this battle in the light of eternity, warning that no temporary pleasure is worth final judgment. Yet the passage does not leave sinners in despair. The same Christ who exposes impurity is the perfectly pure Savior who fulfilled all righteousness, bore the guilt of His people, and gives His Spirit to sanctify them. The call is clear: flee lust, cut off its provision, and follow Christ in holiness before the holy God.
