Back when I was going to church with my family, I remember many talks in youth group. I could usually out Bible knowledge most of the class. But I also remember saying, "Faith and knowledge are not the same thing."
Despite, "Study to show thyself approved unto God, a workman that needeth not be ashamed, rightly divining the word of truth." (Somewhere in II Timothy, I forget the exact verse, if I had to guess I'd say 2:13)
