Wow, such hostility. I think the fact that my responses are much more formal and tactful than your's is evidence that I do not need to "grow up" any, thanks though.
The reason why is very simple, God created everything to bring glory to himself. People modelling His work week brings glory to Him. People anticipating the coming of the Messiah brings glory to Him. People studying His word brings glory to Him. Just for your information the Bible was written in Hebrew and Greek, so I am not sure what God's knowledge of the English language has to do with anything. The chances of man making up a religion that holds such a negative view of man and gives all the credit and glory to someone else seems rather far fetched.
