I agree
@Sue D. very good point about the fine line, I think this is where discernment comes into play.
@Sue D. and
@Bendito , I think when people hear the term demon possessed strong walls come up. I think one can also look at it from an even lesser spiritual perspective
and speak of people under the influence of evil spirits. This is less debatable. For example, a certain Christian may not be "possessed" by a demon (though people can be, and are)
but he or she may be heavily influenced by evil spirits. Do you remember when Jesus told Peter, "Get thee behind me Satan". Are we to think that in that moment Peter was possessed
by the devil? If you say yes, than this should change your perspective on how you think demon possessed people act because on the surface, Peter's request to save Jesus life seemed
logical and common sense. However if you say no, Peter was not demon possessed than you are left with saying he was influenced by the devil in the mind.
Similarly, I think evil spirits put thoughts in our minds just as the Devil did to Peter and Jesus was quick to rebuke Satan. He didn't even talk to Peter, He (Jesus) went straight to the source.
My point is I think looking at this clear Bible evidence that even if someone is not possessed by a demon, many are influenced in their thoughts and likewise these spirits can be rebuked.
@Sue D. once again you mentioned a good point about the fine line, I agree that there are mental issues that are not spiritually related. With that said, I will say that we should be careful
in putting God in a box. Let us not forget that God can heal body, soul, and spirit. Therefore we don't have to ask God for his power for only the spiritual. The early church prayed for common
biological sicknessess, however, now that we have more advancements in science we look as say, I can just take this pill and I can be heal. I'm not taking anything away from modern medicine,
it has its place, I'm just saying that for us to be mindful of not putting God in a box.
Lastly, with drawing that line I think many forget that ultimately we are one. We have a body, soul, and a spirit; they all influence each other. Poor nutrition in the body can impact once
emotional health in the soul. And stress in the soul (mind<not brain>) can lead to physical illnesses (research has shown this). So just because a condition originates in a certain domain (body, soul, or spirit)
it doesn't main that the other domains can't be engaged as well to bring about healing.
I'm not saying everything is spiritual and I'm not saying ignore the blessings of science that God has allowed us to discover. For example, someone may be dehydrated and think they are depressed, but
really it is just poor nutrition and a lack of sleep. If someone thinking that depression is a demon and tries to cast it out (when it is not there) obviously there would be nothing to cast out. However if they
earnestly prayed to God, I believe even in their error, God would lead and show them the answer, whether it is leading them to the right doctor or giving them the insight that their problem was nutritional.
Simply put, even if what we think is the problem is not the problem, God still heals and can still guide.
Final thought with the fine line, I think about Job, and how God allowed Satan to cast sickness over Job. We in the background see that the nature of the sickness was spiritual, though it was
clearly manifested in the flesh. I fear that if that (Job's story) happened today. Many would take Job to the doctors (which is not wrong) and obviously when the doctors would run their test
they would see physical genetic sickness in his body. And since they could perhaps diagnosis it on the body level they would not give a second thought that any spiritual is happening in the background
and also not see any value of Prayer in Job's situation. ---We are also told in the Old testament that God visited curses from generation to generation, were these curses passed genetically in the dna?
That is possible.
So my point is yes, there is a line, however let us not put God in a box. He can heal all. Let us not ignore the science but likewise not compartmentalize God and the spiritual falsely thinking that spiritual things
cannot be manifested in the body. There is so much happening in the spiritual realm that is we could see it, we would be beyond surprised.
