This song actually follows philosophical skepticism more than anything religious. The mention of God isn't so mucha questioning of faith, but of epistemology. He's questioning what he knows, of what he can be certain. The title and most repeated line of the song is "I don't know." What can we really know? The first verse is, in essence, the gist of Descartes' Meditations, particularly the first Meditation. The mention of duality (dualism) follows along with this. I feel this is reflection of philosophical inquiry and uncertainty rather than faith-based or religious.
