God... Truth or fiction?

Of course, to promote one's religion, one must possess charisma. Without it, it's impossible. But Muhammad truly believed that Allah created everything, so he wasn't trying to deceive anyone. He simply shared his faith. Yes, I believe in what is written in the Bible. And the Old Testament is just as important in Christianity as the New Testament. Because it is the foundation. Jews and Christians, as you know, believe in one God; the only difference is that Christians recognized Christ, while Jews did not. That's the only difference (besides some customs and traditions). So, saying that Christians shouldn't use the Old Testament is as silly as telling Saruman not to call himself a Christian because he believes the world was created by an absolute being. Isn't that silly?
