How to convince a poorly educated diabetic patient, of high religiosity, who believes that complications will definitely occur with the will of the God however he does
Probably you should ask him if complication of Hunger will persist by God will without eating! You may also ask him if he may allow you to give him three hot punches on his face and see if he will feel the pain by God's will. I think what he needs most is antidotes to his ignorance, so teach him the fundamental part of his faith known as destiny.
You can pray that "God, grant me a mind free of WORRY, a heart free of SADNESS, and a body free of SICKNESS."
However, God does not micromanage our actions. Prayer by providing hope or by accepting laws of nature changes us and we change things... http://amzn.to/hXsaXR https://books2read.com/b/m2vYPr https://goo.gl/b7MBBg
I think perhaps he misses the idea of compassion to him God’s will is supreme and in control of his destiny. It can be a way to evade personal responsibility and be God’s victim. Maybe offer some religious discussions alongside his notions of God and look for an opportunity to see if he could see God as a compassionate being ready to help him out of this sad situation. Our consideration might be (Who wants him to die his God or himself? ) at some point you might be able to challenge him to See his God’s heart vs God’s rules am I on track here?
