Our good friend Kieren suggested we look at this subject.
I took a look at this link, and I guess the premise is that those experiences of "people of faith", are really explainable by science, and the result of magnetic fields or enviremental or pyschological contexts.
It would seem to me that the result of any such tests, only proves that in some situations some people may have "spiritual" type feelings. This however would not explain my own personal experiences.
I have spent many hours debating the subject of faith with athiests and agnostics. I have also come to the understanding that the basic issue stems from our presuppositions. When we start with an understanding that there is a God we interpret our data, our logic, our facts, and our experiences through the God grid. When someone comes from a place that says there is no God, they deal with life through this grid. The fact that people often switch sides, does not explain away the results of our presuppositional thought. And often our presuppositions are based on things that are not scientifically proven. This is true of the athiest as well as the theist. The athiests cannot prove the non existence of God empirically, nor can the theist prove the existence of God empirically. So we wind up argueing from our own place of faith.
I will say, that the things I have experienced would not be effected by these tests, nor would they be scientifically verifiable. I understand that I cannot expect anyone to take my word for it, but I also believe in the truth of my experiences. Though I have experienced "supernatural" occurences, the greatest truth I can hold on to, is this...
I have changed through the influence of Jesus on my life, I have become a better man, a better husband, a better father, a better human. The fact that others become better without Jesus, does not mean I could have, nor would have without Him. My life has been changed for the better because of Christ. I am more fulfilled, joyful, and selfless. I hope I continue to let Christ change me into His image.
