Most Christian movements believe that God does heal people. Most christian movements accept it as something that we can not control, but for which we can intercede. However some people are skeptical of this, and believe this to be some sort of placebo effect.
Some evangelical movements, like Full Gospel, Pentecostal and Charismatic; believe that healing can be achieved by prayer, faith, and the laying on of hands.
This Doctrine says that Jesus Christ as done everything he needed to do in order to provide for healing, and all we have to do in order to receive healing is to meditate on the Bible and pray with faith to God.Doctrine of Divine Healing
