Matthew Poole and continuators on 1 Corinthians 8:2

2 And if any man think that he knoweth any thing, he knoweth nothing yet as he ought to know .

Let it be in this or any other matter, if any man be proud of his knowledge, and be conceited that he knoweth enough, and needeth none to instruct him, he may indeed have a notion of things, but it will do him no good, a man ought to use his knowledge for the glory of God, and the edification of others. Let a man have never so large a notion of things, if he be not humble, if he useth not his knowledge to the honour of God, and the advantage of others, he knoweth nothing as he ought to know it. Knowledge is a Talent not to be laid up in a napkin.
