Job (who is described as a "perfect and upright man"), talked confidently about how he would declare his case before The Lord and be justified, while he yet was personally unacquainted with His up close and unveiled Presence...but once The Lord appeared immediately before him, his reaction was quite unlike what he had proclaimed it would be... saying -
I have heard of thee by the hearing of the ear: but now mine eye sees thee.
Wherefore I abhor myself, and repent in dust and ashes. <-----> Job 42:5+6
Now, if Job was religiously perfect and morally upright, why was he overwhelmed with a sense of self-abhorrence and need to utterly repent?
Was it not because he underestimated The Greatness, The Power, The Glory, Yea, The Vehemence of The Lord his God ?!!
Did he not wrongly suppose he would met Him as a man, as being somewhat of a peer, or a near equal, one with which he could stand toe to toe and eye to eye with ? Ahhh, but such is not at all the case !!

It's ungodly fear which perfect love casts out.
But being instantaneously struck with exceedingly great fear and soul shaking pangs of terror, at the sight of an Tremendously Powerful, Terribly Hot and Burning Jealous and Most Vehement God is purely a natural reaction to His Revealed Supernatural Self.
Least that's the impression present with this earthen vessel.
