That is a frightening ultimatum afforded between faith and reality. It reminds me of the cause behind the headlines in the link I posted. Children who died because their parents preferred prayer to medicine.We humans have taken God out of the equation for healing. We are negative and lack faith for healing to manifest in our lives. Jesus never once said go to the doctor and I will use them to heal you. We have replaced God with doctors.
When God is omniscient, all knowing, and omnipresent, how can God not be the spirit guiding the hand of that surgeon saving a life from a ruptured appendix? How do we not see God working there when God is a spirit.
When a child has a fever of 102, how can our infinitely powerful eternally present King of Heaven not be the source, the intelligence, that guides the chemist that created that antibiotic, that other medicine, that saves that young life from fever?
When God is everywhere, when God is love, no Doctor replaces God in the healing of the sick and ailing among us. Rather, Doctors and Pharmacists, and all who devote themselves to healing, are those that God sends to answer our prayers. Because it is his anointing that gives them their gift.
How do we think God heals if we do not see God's handiwork, God's eternal power, working through medicine?
