“ And here's something else, another problem you might have: Suppose your prayers aren't answered. What do you say? Well, it's God's will. Thy Will Be Done. Fine, but if it's God's will, and He's going to do what He wants to anyway, why the fuck bother praying in the first place? Seems like a big waste of time to me! Couldn't you just skip the praying part and go right to His Will? It's all very confusing. ”
