The Bible has a lot of stories where people experienced miraculous healing for their sicknesses and other unexplained medical conditions. This has given some people today the idea that doctors and other medical practitioners are unnecessary in seeking treatment and healing.
But if we read in the New Testament, the Lord Jesus Christ Himself said that someone who is sick needs a physician. It means God uses the knowledge and specialization of these professionals in providing healing for the sick.
Even the Apostle Paul had his own doctor, the beloved physician, Luke. He was with him in all his journeys, documenting and possibly keeping Paul’s health in check. Calling a doctor is not a sin, it simply means seeking from someone whom God ordered to be more knowledgeable in medicine than we are.
