If we please God, he will make us wise, understanding, and happy. But if we sin, God will make us struggle for a living, then he will give all we own to someone who pleases him. This makes no more sense than chasing the wind.
For example, some people don't have friends or family. But they are never satisfied with what they own, and they never stop working to get more. They should ask themselves, “Why am I always working to have more? Who will get what I leave behind?” What a senseless and miserable life!
You expected much, but received only a little. And when you brought it home, I made that little disappear. Why have I done this? It's because you hurry off to build your own houses, while my temple is still in ruins.
