Now the souls of the men whose good is sought in this work are no less precious in the sight of God, though they are unacquainted with philosophical terms and ways of arguing, than the souls of the most learned. Besides, that which we account our wisdom and learning may, if too rigorously attended, be our folly. When we think to sharpen the reason of the Scripture, we may straiten the efficacy of the spirit of it. It is oftentimes more effectual in its own liberty than when restrained to our methods of arguing, and the weapons of it keener in their own soft breathings than when sharpened in the forge of Aristotle.
John Owen, From the epistle dedicatory prefixed to The Doctrine of the Saints’ Perseverance.
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. Unbelievers, some of them, may know more and be able to say more of God, his perfections, and his will, than many believers; but they know nothing as they ought, nothing in a right manner, nothing spiritually and savingly, nothing with a holy, heavenly light. The excellency of a believer is, not that he has a large apprehension of things, but that what he does 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.
