"If He is not is us, we lie and do not pursue the truth..."
Indeed, if we believe in more, then there is something more to be serviced than a fixed object of belief, and it is reflected, filtered into our words, that there is something set and real in the universe, and all is not a dream.
Plato's objective universe, mayhap, and the Roman stoic's formal universe. Truth that superceeds and eclipses the shifting sands of what we call reality. Something fixed and solid.
