I love the sweeping promise of 33.3. And it has little do with answers to our prayers. It has everything to do with revelation. He promises to reveal to us things that we don't know.
Answers? Yes. But revelation. That's where the life is.
Because there are days when there are no easy answers. There are days when there are no answers at all. No one can answer the "why." No one can predict the "what's next."
But to hear God say, "I'm faithful." To hear the thunder of, "I'm in control." That's life.
