This is a question to all Christians out there (but Muslims or Jewish people are free to respond as well):
How do you know the God you support (the God from the Bible) is this good guy and not the evil guy? See, there is a fundamental issue here: the only source that supports claims that your God is the good one is the Bible. The Bible was written centuries ago by relatively unknown sources.
So how do you know you're not being duped? What if the devil is actually the good one?
How does one resolve this issue?
