Read the story of the Christian African nurse who recovered. She had no IV like the lucky patients here, so she would literally sit on the can and force down the liquid drink (forgo the name) that helped her survive.
YEah, I read that story. Drank gallons and gallons of their version of Pedialyte, basically an oral rehydration therapy. She willed herself, along with the power of prayer, and the protection of the Holy Spirit, from just laying down and dying. I think she said something like the ORT therapy helped as much as prayer did.
