We have in the cross, the clearest and most obvious fingerprint of God. He made this up, and He executed it by His own sovereign power. You yourself did not make this up, you would never have made it up. There is a strange comfort in saying that the whole thing seems a little alien and creepy, because it means we didn’t invent it. No human invented your salvation.
There is a hole in our gospel because we are ashamed of the cross. We want to make the root Christian message into something we do for God. The gospel is actually the message that God has done something for us. All of this talk about sin and wrath and blood and crosses is a bit embarrassing. We want to get on with the practical stuff. I’m here to say that we need to give far more attention to what we have heard — that we have such a great salvation (Hebrews 2:1-3)!
