Proverbs 18:2

A fool may pretend to understanding, and to seek and intermeddle with the means of it, but, 1. He has no true delight in it; it is only to please his friends or save his credit; he does not love his book, nor his business, nor his Bible, nor his prayers; he would rather be playing the fool with his sports. Those who take no pleasure in learning or religion will make nothing to purpose of either. No progress is made in them if they are a task and a drudgery. 2. He has no good design in it, only that his heart may discover itself, that he may have something to make a show with, something wherewith to varnish his folly, that that may pass off the better, because he loves to hear himself talk.
