I believe God is real and good. I'm a Libertarian myself, but at least I can acknowledge my God is not.
As a former Libertarian I can respect your opinion. As a realist I have to tell you that the best logical assumption is agnosticism. None of us know anything for certain.
What do you mean that nothing can be known for certain? Do you mean about God, or about anything at all?
About anything unseen. God, aliens, bigfoot, etc. Its best to say "I don't really know for a certainty if they exist".
I agree that we don't know for certain whether there is any sort of ethereal consciousness we can pray to or communicate with. But I think certainty about the existence of God depends on how you define "God."
Are you certain that none of us knows anything for certain?
faith is the evidence of things unseen.
