Jesus wasn't surprised

"He committed no sin, neither was deceit found in his mouth. When he was reviled, he did not revile in return; when he suffered, he did not threaten, but continued entrusting himself to him who judges justly. He himself bore our sins in his body on the tree, that we might die to sin and live to righteousness. By his wounds you have been healed."

- 1 Peter 2:22-24

 

"In John 10:18 Jesus said, "No one takes my life from me, but I lay it down of my own accord. I have authority to lay it down and authority to take it up again." Those very significant words of Jesus mean that everything that happened to him on that first Good Friday—all of the physical pain of the whippings, the beatings, the crown of thorns thrust into his head, the nails driven into his hands and his feet; all of the emotional pain of being mocked and spat upon; all of the spiritual pain that Jesus endured when his Father turned his face away from him as he took upon himself the sins of the world—all of it was voluntarily accepted and voluntarily endured by Jesus Christ for the glory of his heavenly Father and for the eternal well-being of his people. Nothing that happened to Jesus that day caught him by surprise. None of it was unforeseen. All of it was anticipated and taken into account by Jesus when he made that fateful prayer in Gethsemane, "Not my will but yours be done" (Luke 22:42)."
