I tried to understand all that happens on earth. I saw how busy people are, working day and night and hardly ever sleeping. I also saw all that God has done. Nobody can understand what God does here on earth. No matter how hard people try to understand it, they cannot. Even if wise people say they understand, they cannot; no one can really understand it.
Ecclesiastes 8:16-17 (NCV)
Do not worry about what happens in this world or even what God is up to. His ways are above our ways, and He is able to use all things for His good.
