“Therefore be careful to observe them; for this is your wisdom and your understanding.”
Wisdom is not what you know about the world but how well you know God. Human reasoning will not make you wise. It may even lead you to reject the ways of God (1 Cor. 1:18–25). God’s purpose in creating a nation for Himself was to demonstrate His wisdom to the world through the obedience of His people (Zech. 8:23).
