Many people said they were cured of cancer by Jesus Christ through him. Wigglesworth, whose only training was as a plumber, described cancer as "a living evil spirit", and insisted that many diseases were "Satanic in origin". His methods often involved hitting, slapping, or punching the afflicted part of the body. On a number of occasions his approach to persons suffering from stomach complaints was to punch them in the stomach, sometimes with such force that it propelled them across the room. When challenged on this, his response was "I don't hit them, I hit the devil". Responding to criticism over his method of praying for the sick, Wigglesworth stated: "You might think by the way I went about praying for the sick that I was sometimes unloving and rough, but oh, friends, you have no idea what I see behind the sickness and the one who is afflicted. I am not dealing with the person; I am dealing with the satanic forces that are binding the afflicted". On one occasion Wigglesworth declared to the sick "I'll only pray for you once, to pray twice is unbelief". The second night, a man approached the altar to receive prayer again and Wigglesworth, recognizing him, said "Didn't I pray for you last night? You are full of unbelief, get off this platform!"
