Something in your post strikes me as very contradictory. You say that you have spent a lot of time thinking about God and the Meaning of Life, however, you keep quoting the Bible, which is only one source of religious philosophy. That is like me saying how I have spent a lot of time analyzing Kafka's works, but then quoting what his publisher and friend Max said about his works. To think means to create your own opinion. What the Bible says is not your opinion.
Every idiot can quote the Bible.
Also, you seem to be concetrating on the Christian view of religion. As someone already pointed out, Judism gives us a different point of view on religion, and so does Islam, Hinduism and other religions.
