That is a very good tutorials I believed some christian prefare prayers to hospital when they are sick also in some countries they prefare traditional way of healing for their health needs
A far better approach is to take advantage of modern medicine when you get sick. Medicine is good at managing and mitigating serious illness. If you develop a major medical problem the best person to see is a physician as that will be the person with the best chance of helping you.
Prayer has its place but praying for divine intervention instead of going to the doctor is a lot like praying for divine intervention to stop the flooding caused by a broken pipe. Nothing is impossible but a better outcome will likely result from finding and shutting off the water main.
