"So, in reading and studying the Bible, we ought to make every effort to search for the revelations of the glory of Christ in it as did the prophets of old. The glory of Christ is the 'pearl of great price' which we should make every effort to find (Matt. 13:45-46). And the Scripture is the ocean into which we dive to discover this pearl, or the mine in which we dig for its precious treasures (Prov. 2:1-5). Every sacred truth that reveals something of the glory of Christ to our souls, is a pearl or precious stone which enriches us. But when the believer discovers this pearl of great price itself, then his soul cleaves to it with joy."
—John Owen, The Glory of Christ (p.33)
