We all have such a limited view of everything. We only know of our own experiences, and our world view is colored only by that which we know and understand. It is as if we can only describe things from our point of view in the universe.
God uses people. Why He chooses to do this is beyond the scope of this post… but a question I often ask. He uses people with all their flaws, shortcoming, and lack of perspective. Sometimes He does this not inspite of, but because of these things. I believe this is the most important reason that the Bible was written by so many different people over such a long period of time. There is no way to paint God with a single color, so He revealed Himself and His plan through history and through so many people so that we might understand Him better.
