For a lot of people, God is a simple, easily understandable entity. Like God is a Guy, with a long beard etc. etc. as they portray in 'The Simpsons'. It is not that simple. Where does God exist when all space and time is created by God. What about existence when God himself created existence. God created gender for propagation of life. He himself is not restricted to a specific gender. Human beings cannot even begin to fathom what God is. We have not been given the intellect. We have our limitations. It's like some guy lost in a huge, dense and dark forest and then he lights a match. He is only aware of the existence of what he can see in the dim light of that match. This is our understanding of this vast universe. Trying to make sense of what God is way beyond that.
Jesus said, "The sin of the world is unbelief in Me."
OK, let's posit I believe he exists? Existed?
Therefore I have no sin, and can go to heaven without having to ever hear another word about the matter. I sure did waste a lot of time in Sunday School in my youth as they nattered on about more trivial points.
