Humble knowledge of self is a surer path to God than the ardent pursuit of learning. Not that learning is to be considered evil, or knowledge, which is good in itself and so ordained by God; but a clean conscience and virtuous life ought always to be preferred. Many often err and accomplish little or nothing because they try to become learned rather than to live well.Thomas A Kempis quoted From the Library of A.W. Tozer
If men used as much care in uprooting vices and implanting virtues as they do in discussing problems, there would not be so much evil and scandal in the world, or such laxity in religious organizations. On the day of judgment, surely, we shall not be asked what we have read but what we have done; not how well we have spoken but how well we have lived.
Wow, this hits kinda hard! I think Paul summed this up in his first letter to Timothy.
 The aim of our charge is love that issues from a pure heart and a good conscience and a sincere faith.  Certain persons, by swerving from these, have wandered away into vain discussion,  desiring to be teachers of the law, without understanding either what they are saying or the things about which they make confident assertions.
(1 Timothy 1:5-7 ESV)
