Thank you for the replies. Yes this is what frustrates me about that side of the argument. I can't get this person to see that strictly human involvement is fixing their problems, not divinely inspired mediums.
This is something now I can say now that plain stumps me. Of course it is reasoning like this why we have to call out logical fallacy. There is no way to argue against circular reasoning because it will always answer itself, even with contradictions.
More disturbing is this: this is an intelligent person. This is not a person that wasn't educated, or can't use logic to solve problems. Quite the opposite is true. How could an ideology be so power to render this person dumb to logical reasoning on this one subject? More importantly, what could be doing it?
This is dangerous territory. Here you have someone that holds the "Daddy can do no wrong," mindset. When that happens in abusive human relationships people get hurt.
My final thought is I have to agree with what a few have said here. That is we must point out the negative results of god's influence with everything in this world. The person in my scenario feels that no matter what I said, god influenced all the positive science that healed their sickness, even if a doctor actually did the work. So my argument should be to corner them into admitting that god touches everything in this world, influences every outcome. If they agree to that it is simply a matter of pointing out the millions of instances where god influenced death, rape, torture, or by lack of influence allowed these atrocities to go on. Then watch as they try to dig themselves out of the hole they fell into.
