If Jesus is God then we need a normal human who isn't God to intercede with Him and represent normal humans with Him - someone like a pope say - hence there are many who love such doctrine - Truth is, Jesus was always human and normal from before time but hidden from sin until He was sent. This is why He is called the Son of Man. That is why, as Enoch explained, He was hidden by God - he was hidden away from corrupting influences and events in the world so He would be perfect to be born into the world - Jesus Christ. He was the Son of Man before His coming in Bethlehem so this means He was always human even in heaven before He came and for this reason God hides Him away to spare Him the constant temptation a human suffers -yet for a few decades He did suffer the temptations we suffer so He knows what it is like and this is what is so important about Him being the Son of Man.
