I could argue the Christ becoming man for 30 some years is meaningless in terms of his God position. He was and is always God. Yes he suffered, but he always was God.
If Jesus is G-d, then how can he die? G-d cannot die. (He cannot be born either.)
In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made. In him was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.
(John 1:1-5 KJV)
The ‘loss’ was for a moment, and through the death and resurrection of the Son, many in the World were ‘gained’ by being reconciled to the Father. ‘For God so loved...that he gave his only begotten Son...’ Note also that the only way this could be ‘loss’ is if there were no resurrection.
We do know that Jesus exhibited human emotion. When told that Lazarus had died, ‘Jesus wept’.
