It's OK to Ask God Tough Questions

From Chosen: The Story of God and His People:

There is no question so out of line that you should not ask it. The people who wrote the Bible asked God some hard questions. They did not hold back out of fear that questions showed lack of faith or respect. They knew God wanted them to be honest with him and with themselves. There is no way you can grow in understanding or faith if you do not ask the questions that need asking.

At the time of the exile in the Old Testament or the time of the crucifixion [of Jesus] in the New Testament, it was hard to see God at work in the world. There are similar times in our own lives. But the Bible tells us he is present, working with us, even in those difficult times when it is hardest to believe this.
