How do we know Jesus heals completely?

The account of Jesus healing Simon's mother-in-law illustrates that His cures are both immediate and complete. When He lifted her by the hand, the fever left her, and she was restored not just physically but also empowered to serve immediately. This reflects a deeper truth about Christ's work in healing sin-sick souls. He does not merely alleviate the symptoms of our spiritual illness but transforms us, granting us a new heart and enabling us to live in obedience and service. Thus, those who are healed by Christ experience not only forgiveness but also the power to lead a life that pleases God.
