what does the bible say?
The Bible offers much help in understanding God's ability and purposes for healing. First, it is clear that God can heal in any way and at any time He desires. He can heal instantly or in stages. He can heal ailments people have had from birth, for many years or for not long at all. Sometimes His healing requires the one healed to take some sort of action and sometimes not. Second, the Bible reveals that God sometimes chooses not to heal in this life. Jesus healed many with sicknesses in this account but left others who had not yet received healing.
