Knowledge

Something I struggle to remember with my doctrine-oriented mind: 

"The difference between believers and unbelievers as to knowledge is not so much in the matter of their knowledge as in the manner of knowing. . . .

 The excellency of a believer is, not that he hath a large apprehension of things, but that what he doth apprehend, which perhaps may be very little, he sees it in the light of the Spirit of God, in a saving, soul-transforming light; and this is that which gives us communion with God, and not prying thoughts or curious-raised notions."
