Barnabas Piper clarifies the difference between asking questions and being a skeptic:
There’s a fine line, though, between being someone who questions things and being a skeptic. In fact, many people would call someone who questions everything a skeptic.
Here’s the thing; I don’t think many skeptics actually question anything. They may phrase their challenges as questions, but their heart is set on rejection and disproving. To truly question something is to pose questions to it and about it for the sake of understanding. This may lead to disproving or rejecting, but the heart behind it is in learning.
And in this sense, we ought to question everything…. [W]hat is more important than seeking every ounce of truth in an established reality? And what is more harmful than abiding in that reality if no truth is to be found there? And so we must question.
