Reason number sixteen we are sure it is God’s will for all to be healed is because we have been given authority over demons and over disease. Jesus told us in John 14:12. He said, “He that believes on me, in My name, the works that I do shall he do also; and greater works than these shall he do because I go to My Father.” Mark 16:17-18 says, “ And these signs shall follow them that believe. In my name shall they cast out devils; they shall speak with new tongues. They shall take up serpents; and if they drink any deadly thing, it shall not hurt them, They shall lay hands on the sick, and they shall recover.”
