The point of these verses is this: Because the Scriptures are the Word of God — the communication and revelation of the living God — they have effects on us that are better than the effects of anything else we can read or study or watch or listen to.
God understands you better than anyone else. He knows how people get to be the way they are and how they are affected by their surroundings. God understands society perfectly. God knows all facts about how the world works. God knows the future and how everything will come out in the end. God is wiser than any wise writer. God is more caring than any counselor. God is more creative than any artist. It simply stands to reason that what God says will be more useful to us than what anyone else in the universe has to say. Not to sit at his feet and soak our minds with his wisdom is sheer craziness
May God increase your confidence that the Bible is his very word! And may that persuade you that by meditating on it and following it there is great reward — greater than much fine gold. And may you discover every day the benefits of life and wisdom and joy!
Psalm 19:7-11 (ESV) - 7 The law of the Lord is perfect, reviving the soul; the testimony of the Lord is sure, making wise the simple; 8 the precepts of the Lord are right, rejoicing the heart; the commandment of the Lord is pure, enlightening the eyes; 9 the fear of the Lord is clean, enduring forever; the rules of the Lord are true, and righteous altogether. 10 More to be desired are they than gold, even much fine gold; sweeter also than honey and drippings of the honeycomb. 11 Moreover, by them is your servant warned; in keeping them there is great reward.
