I think it helps to keep in mind that Jesus was both fully human and fully God -- not just God in an earth-suit. It's a mystery, yet it helps us to understand what he went through.

"Think of yourselves the way Christ Jesus thought of himself. He had equal status with God but didn't think so much of himself that he had to cling to the advantages of that status no matter what. Not at all. When the time came, he set aside the privileges of deity and took on the status of a slave, became human! Having become human, he stayed human. It was an incredibly humbling process. He didn't claim special privileges. Instead, he lived a selfless, obedient life and then died a selfless, obedient death—and the worst kind of death at that—a crucifixion" (Phil 2:5-8, MSG)
