What does Proverbs 3:19 mean?

To emphasize the extraordinary magnitude of God's wisdom, Solomon appeals to creation. We can only stand in awe of God's creative wisdom. We see signs of it everywhere, from the hummingbird to the Himalayas, from the human body to the heavenly bodies, from the earth below us to the sky above us, from the bluebird to a sunburst, from a minnow to a manatee, and from a rainforest to a rainbow. Only the all-wise God could create such a diverse universe. Psalm 19:1 presents the potent testimony of God's creation: that which God created "declares" His glory.

In the book of Job, God answers Job's struggling questions by reminding him of this same idea. Out of the whirlwind, God asked: "Where were you when I laid the foundation of the earth?…Who determined its measurements…" (Job 38:4–5). No one can fathom the depths of God's wisdom (Isaiah 55:8–9), yet He condescends to share some of His wisdom with those who trust and obey Him. James 1:5 states: "If any of you lacks wisdom, let him ask God, who gives generously to all without reproach, and it will be given him."
