In that regard, I urge you to read a recent blog post from John Piper. Here's a snippet:
God cannot make plain all he is doing, because there are millions and millions and millions and millions of effects of every event in your life, the good and the bad. God guides them all. They all have micro purposes and macro purposes. He cannot tell you all of them because your brain can't hold all of them.
Trust does not demand more than God has told us. And he has given us immeasurably precious promises that he is in control of all things and only does good to his children. And he has given us a very thick book where we can read story after story after story about how he rules for the good of his people.
Let's trust him and not ask for what our brains cannot contain.
