You Can't See God, but You Can See Where He's Been

There's a passage in the book of Exodus in which Moses wants to see God's glory, and God agrees to pass by Moses while shielding Moses' eyes with his hand. God then says, "I will remove my hand and you will see my back."

Rob Bell, in his book "Velvet Elvis", says:

The ancient rabbis had all sorts of things to say about this passage, but one of the most fascinating things they picked up on is the part about God's back. They argued that in the original Hebrew language, the word back should be understood as a euphemism for "where I just was".

It is as if God is saying, "The best you're going to do, the most you are capable of, is seeing where I ... just ... was."

That's the closest you are going to get.
