Knowledge puffs up. Why are we such know-it-alls sometimes. Have we not heard enough that GOd is completely repelled by the proud. Knowledge is good but it can never take the place of the real definition of what it is top be spiritual: loving God and being known by Him. Besides, "I don't know" is actually a pretty valid answer. It puts us in the position to be teachable, to hear what God has to say about our situations. Having a relationship with God fueled by humility means we aren't in a position of thinking that God is impressed by what we know. He'd much rather be a father and the recipient of our questions.
