"If I go to the doctor, I am putting the doctor before God," Neumann said. "I am not believing what he said he would do."
Quote taken from here.
Seems another sad case where a child has died due to perhaps well intentioned but misinformed parents. While it's true that God is ultimately sovereign over all and desires that his people call on his name, that doesn't negate the fact that God also provides and works through means (such as doctors, medicine, etc.) and calls for man to act wisely. The fact is that while some may do things as if to serve God, that doesn't substitute for being transformed in the renewing of one's mind so that one is a ble to test and approve what God's will his, his good, pleasing and perfect will.
Consider such things as:
1. God reveals wisdom not only through Scripture but also general revelation.
2. Luke was a doctor
3. Many passages in Scripture where not only prayer was offered but steps taken, salve and balm applied, etc.
Bottom Line: Divine Provision does not deny Human Responsibility
While unbelieving apologists will capitalize on this case as they have others, it should be pointed out that the error here is found with the individual and not either the truth and practice set forth in Scripture or in the vast majority of those who ascribe to Christian beliefs.
