If someone is not giving the kind of evidence that actually proves something, I am going to point that out. It doesn't mean I'm opposed to faith. I actually support faith. What I'm against is people saying that they have faith because X proves it. For one thing, if it is proven, it doesn't take any faith.
Let me give an example of what I mean. When I was 15, my Sunday School class began reading a book together by Josh McDowell called "Evidence That Demands a Verdict." Now at that time, I was a firmly convinced Christian, so the reasons for my reaction CANNOT be blamed on my wanting to undermine Christianity. Basically, I was appalled by the book.
The small reason was because even at age 15, I could see all sorts of holes in his reasoning, and I can't tell you how discouraging it is when your Sunday School class is given something so sloppy to study--it's embarrassing on behalf of my religion.
But by far the deeper reason I was disgusted with the book is because it confused faith with things we accept as true because the odds that they are true are so high. To me, that's not faith. That's reasoning.
Faith comes from an entirely different area in our minds than the reasoned truths that we accept. It's not that it doesn't have some interaction with our reasoning--but the reasoning is not what is primary. Faith comes from what we intuit. It springs from the same part of the mind that governs analogy and metaphor and patterns--an entirely different kind thinking than logic. It is far more related to poetry and art than it is to logic. Faith is beautiful, and meaningful, and precious. But it is NOT based on "evidence that demands a verdict."
