We all know God cannot look upon a sinful person hence Christs sacrifice for us, hence when Jesus was on that Cross carrying the sins of " all men", God could not be with Him nor look upon Him, it is His Holiness and Righteousness, remember what He said to Moses,
Exo 33:20 And he said, Thou canst not see my face: for there shall no man see me, and live.
Exo 33:21 And the LORD said, Behold, there is a place by me, and thou shalt stand upon a rock:
Exo 33:22 And it shall come to pass, while my glory passeth by, that I will put thee in a clift of the rock, and will cover thee with my hand while I pass by:
Exo 33:23 And I will take away mine hand, and thou shalt see my back parts: but my face shall not be seen.
One can only presume that if Christ was to look upon the father while in His " sinful" state he would have ended up the same way.
