You should THANK God for givin' the doctors/scientists some skills to save people's life. God gave doctors/scientists good hands to perform skillfully.
If, God/Jesus is NOT the doctor - then, there will be no doctors anywhere.
Yes true, God/Jesus is my doctor. When I was at near death from my own illness at two years old, my doctor could not saved me and told my mother to prepare to let me go since the dr gave up hope for me. My mother could not bear to see me in so much pain and asked God to take me home. I was with Him then He send me back here to my body with golden light swirling around and into my body. That is how I got healed, no doctor could saved me since he lost about 6 kids at the same time except for me.
