We have taught that we can not separate our Soul to our body and if it does, death when we heal the physical body from any illness we should also treat our soul to be strengthened.
Many people think that our soul is external part of our existence. But what we do not realize is that our mental intelligence and emotions is the expression of our souls into our being.
When the Physical doctor fix our body by giving medicine, Spiritual doctors must fix also the mind and emotion of the patient. Thus praying for the sick helps fast recovery as you place the patients conscious mind into God’s grace thus developing new hope for the patient to recover past.
