WHY DO WE DO THIS?
In the Bible Jesus Christ healed all who came to him with all manner of sickesses and diseases.
He taught his followers to do the same after he was gone. He has given Christian disciples delegated power and authority to accomplish this. Therefore we're only doing what he told us to do.
