Religion, the accepted insanity.
Humans cannot change Who God Is. They can represent (or misrepresent) Him.
If God is anything like what some religions say He is like, He isn't worth knowing. Why would you want to know a psychopath? The people who follow the religion are a guide to the apparent truth of the religion . For God to be worth knowing the individuals Who claim to represent Him must be worth getting to know. If they are not worth getting to know, chances are pretty high that the God of that religion is not worth getting to know.
If you get a sense that the people have a genuine love towards you that is not faked, chances are that the religion is probably true.

1 Peter 2:1
