I shudder to think of what happened to one who tried:
Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness: I will cast thee to the ground, I will lay thee before kings, that they may behold thee.
Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick; therefore will I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee.
All they that know thee among the people shall be astonished at thee: thou shalt be a terror, and never [shalt] thou [be] any more. - Ezekiel 28:16-19
Wilt thou also disannul my judgment? wilt thou condemn me, that thou mayest be righteous? Hast thou an arm like God? or canst thou thunder with a voice like him?
Deck thyself now [with] majesty and excellency; and array thyself with glory and beauty. Cast abroad the rage of thy wrath: and behold every one [that is] proud, and abase him. Look on every one [that is] proud, [and] bring him low; and tread down the wicked in their place. Hide them in the dust together; [and] bind their faces in secret.
Then will I also confess unto thee that thine own right hand can save thee. - Job 40:6-14
Absolutely, A-G! We see "as if through a glass, darkly." For any man to say he knows God, His Truth, His Will, His Purpose, or His Methods fully, completely, is absurd -- and most likely culpable.
