How do we know Jesus heals and cleanses sin?

We see from the story of the leper that the healing is not merely a physical act; it is deeply tied to the theme of spiritual cleansing. In the narrative, the leper’s physical state – a manifestation of his uncleanliness – parallels the sinful condition of all humanity. Just as the leper approached Jesus in desperation, acknowledging his need for healing, so too must we recognize our need for spiritual cleansing. Jesus's response, 'I will; be thou clean,' signifies His authoritative power over both physical and spiritual decay. Through His sacrificial death and resurrection, Jesus fulfills the ultimate need for cleanness, offering His people freedom from the bondage of sin. His willingness to touch the leper reflects the intimate nature of God's grace towards us, emphasizing that while sin is rotten and contagious, Christ engages with it fully to bring healing and restoration.
