In the spirit of Matthew 25:34-40. What I mean by surprised is that Jesus can and does expierience joy. I don't mean Jesus was caught of guard. Did Jesus' humanity ever have an expierience of not expecting something? Probably. Hebrews 4:15 For we do not have a high priest who is unable to empathize with our weaknesses, but we have one who has been tempted in every way, just as we are—yet he did not sin.
