The role of a physician is to be God’s messenger to heal. We are allowed and should go to the doctor when we are ill but even on the ordinary level the doctor got permission from God to heal as God said “I am God, your Healer” Exodus 15:26. God does not need man to cure the afflictions that he creates.
Some health problem come and go as a mystery without any physical/medical involvement and sometimes even in opposite of doctor’s diagnosis that healing was not possible, they call it a “medical miracle”.
When recovery what done above nature, without any reason, change or action from human beings involvement or knowledge, the person’s life whole life is turned around as a gift.
