My belief in the supernatural, God, is solely because of faith. I know that, and recognize its weakness as an argument. However, my experiences inform me that it is true. They are basically non-repeatable, though, and materialists could offer other explanations, including statistically improbably coincidences.
It works for me, though, and if it doesn’t work for you, that is between you and God. Or not.
What’s mind? No matter.
