Of course, it's also true that suffering and death were made more difficult for Jesus than it is for us because, from the evidence of the Gospels, He knew far in advance of the events just how horrible His death was going to be and exactly when it would happen. It was by His deity that Jesus knew these things and it was this fate He prayed to be spared and then accepted in His prayer in Gethsemane.
He forged ahead to the cross (Luke 9:51), despite. As God, He was, as Lewis says, armed with the foreknowledge that if He fulfilled His mission, dying and rising, He could offer new life to all who repent and believe in Him. Only God could save us from sin and death. We should be glad to accept this help from the one who is stronger than us.
