Did you ever think, when you were a child, what fun it would be if your toys could come to life? Well suppose you could really have brought them to life. Imagine turning a tin soldier into a real little man. It would involve turning the tin into flesh. And suppose the tin soldier did not like it. He is not interested in flesh; all he sees is that the tin is being spoilt. He thinks you are killing him. He will do everything he can to prevent you. He will not be made into a man if he can help it.
What you would have done with that tin soldier I do not know. But what God did about us was this. The Second Person in God, the Son, became human himself: was born into the world as an actual man–a real man of a particular height, with hair of a particular color, speaking a particular language, weighing so many stone. The Eternal Being, who knows everything and who created the whole universe, became not only a man but (before that) a baby, and before that a fetus inside a woman’s body. If you want to get the hang of it, think how you would like to become a slug or a crab.
The Man in Christ rose again: not only the God. That is the whole point. For the first time we saw a real man. One tin soldier–real tin, just like the rest–had come fully and splendidly alive.
