The quick answer is: No, the Christian God is not better than no God at all. In other words, not believing ANYTHING about God is better than believing the wrong things about Him. Believing the wrong
things about Him makes one a hypocrite. How?
Because of the common heresies (eternal torment being one of them), one proclaims a God of unconditional love and grace but then delivers a god who damns to eternal pain those who do not love Him. Excuse me, but: How is this unconditional love?
Those heralding a false God (all of Christianity), like the Pharisees, make their "converts" into worse people than they. How? They compound the sins of the uninitiated by adding to their status quo sins the immense unrighteousness of hypocrisy, self-righteousness, worry, fear, and—really—idolatry.
Other than that....
