And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies through his Spirit, who lives in you. Instead, be filled with the Spirit. You, however, are controlled not by the sinful nature but by the Spirit, if the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, he does not belong to Christ. Sickness is only the penalty of physical transgression, and whenever one is sick, he is paying that penalty.
Healing is nothing more or less than the forgiveness of sin.
Scripture labels other modes of healing idolatry. If we claim we have not sinned, we make him out to be a liar and his word has no place in our lives. If we claim to be without sin, we deceive ourselves and the truth is not in us. All wrongdoing is sin, and there is sin that does not lead to death. Anyone, then, who knows the good he ought to do and doesn't do it, sins.
