And I wonder why would God want to arbitrate over matters of "right world view"?
Or is God an American?
Because God is holy, and has no sin, He cannot lie. If something, anything, is wrong or untrue, it is against God.
Because of His love, and mercy, and grace, He wants to help every individual walk in that same truth and light.
How would we know what God was like, unless He chose to reveal Himself to us?
Which He did.
