In this episode of Healing School, Justin delves into scriptures like Isaiah 52 and 53 to argue that Jesus was made sick and bore diseases as a substitute for humanity, thereby providing a foundation for believers to claim their healing. Justin explains that just as Jesus was a substitute for sin, he also was for sickness and disease, drawing a direct connection between Christ's atonement on the cross and the deliverance from physical ailments. He challenges any skepticism about healing by suggesting that it is as much a part of the gospel as salvation is.
