On the contrary, unbelief, is the lack of faith in Him, placing our personal arrogant understanding as senior to His provision. It is not brutally honest, but boldly arrogant and deceiving to the person who turns any direction but to God.
Boldly arrogant is a claim that something inconceivable, invisible, unimaginable, unrecognizable exists because it "revealed" itself to us.
It is even more arrogant to say that this inconceivable, invisible, unrecognizable, uncrimcumscribed, amorphous, bodiless, ontologically incompatible existence dwells inside those who who "hear" and "see" it.
