According to the Bible, believing certain propositions is of eternal consequence. Consider Hebrews 11:6
"And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him."This verse notes that at the very least one must believe at least two propositions. One of those is that God exists. Yet without correctly apprehending what God is or how God is, how does one believe this very basic proposition?
