Imagine there's the most beautiful toy store, with everything you could ever want. But when you go to buy Wisdom (so you don't make mistakes anymore), real Joy (not the fake kind), guaranteed Health, or Peace in your heart (the kind that helps you sleep well), the saleswoman says: "We don't have that here." Because those things aren't for sale!
The Bible says it's God who gives Wisdom and Understanding. He opens His mouth and gives away for free what nobody can buy. And the best part: Jesus came to bring all of this into our lives. We don't need more money to be rich on the inside!
