No body Truly knows G-d.
True blasphemy is proclaiming you do know G-d and not admitting how incredibly ignorant you are compared to such a Glorious Name.

Had you understood the Great Mystery, you would not be here on an online forum proclaiming to everyone how Holy you are.

The mystery of G-d's name shall not be made known to anyone until the final Revelation. Anyone who claims to know this mystery while on Earth, is a false prophet.

Even Christ Himself struggled with the Will of G-d until his body was delivered the cross and he was freed of his false self.

"Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done."
