The paradigm of God created by the Jehovah's Witnesses, however, is quite foreign to many other people who accept the existence of God.
Judaism and Christianity, unlike the Witnesses, did not begin with a set of Scriptures upon which their religions developed. Judaism composed its text gradually and assembled the canon of the Hebrew Bible only after their return from Babylonian captivity. Christianity had no New Testament until the Gnostic Marcion of Sinope created his heretical canon of an edited form of Luke and some of the Pauline epistles, claiming for the first time that doctrine had to based on "inspired texts."
Neither of those religious systems are based on the Scriptures. Instead, they composed and assembled Scriptures that reflected what they already accepted and practiced. That is very different from the Witnesses who follow in the path of Marcion.
Many Jews don't believe in life after death. Their religion teaches them to be grateful for the life they have now and to work to bring healing into the world to people of all races. And while many of them and most of Christianity holds some sort of hope in a future life, they are taught never to live only for then. "If you aren't happy with and focused upon the life God gives you now," my Catholic friend Carlos is fond of saying, "God is certainly not going to give you more tomorrow."
While I am all for applauding your choice of rejecting religion and God, and I will always defend the right of conscience of anyone who chooses to freely do so, I am merely saying that we should not be so quick to think other religions hold the views we were taught they do by our former education in the Watchtower. They don't all believe or hope in another life after this one or think all you have to do is believe and be saved. Some have no concept of salvation, like Judaism. And while some people do base their beliefs solely on Scripture, the majority belong to religion that composed Scripture, having beliefs and doctrines and practices that are far older than what is written.
We can still reject God and religion without jumping to the conclusion that we know what everyone believes and hopes and where they get their beliefs. We can be atheist without being judgmental like some religions, like the JWs, and condemn the rest of humanity as being in a cult.
After all, didn't we just come out of a group that taught us to think like that? Why do we want to imitate their judgmental and intolerant ways? I am sure you don't.
