One problem I have with faith-healing is that it tends to be focused only on the physical aspect of healing. But Jesus always backed away when people came to him only to get their physical needs met. My goodness, he was ready to have you lop off your hand! His real interest was in healing the soul.

Joni Eareckson TadaThe truth of the matter is, Satan and God may want the exact same event to take place - but for different reasons. Satan's motive in Jesus' crucifixion was rebellion; God's motive was love and mercy. Satan was a secondary cause behind the Crucifixion, but it was God who ultimately wanted it, willed it, and allowed Satan to carry it out. And the same holds true for disease.
