Absolutely Christians need to seek Doctors and physician for treatment.God created us in different functions to help others and God Used the medical personel to treat people but as a christian we have faith God healed us and the medicine and the Doctors we pray as God used them as an instrument.Only wrong if a christian treat the Doctor or medicine as God.Eveything we do we acknowleged God and if we healed from sickness all the praises and thanks giving only God are worthy and of course we gave thanks also to the people God used for it.(doctors)
