Jesus Christ was on the road to the incarnation while Adam was a mere thought in the mind of God. For there could not possibly be a union between God and humanity except through a staggering act of stooping on God’s part. Before creation, our adoption—and its accomplishment in Jesus Christ—was raised as the banner of all banners in heaven. It was not the Fall of Adam, therefore, that set God’s agenda; it was the decision to share the great dance with us through Jesus. Adam’s plunge certainly threatened God’s dreams for us, but that threat had been anticipated and already strategically overcome in the predestination of the incarnation. Jesus Christ did not become human to fix the Fall; he became human to accomplish the eternal purpose of our adoption, and in order to bring our adoption to pass, the Fall had to be called to a halt and undone. The catastrophe of Adam certainly made the road of incarnation, and thus of our adoption, one of pain and suffering and death, but it did not create its necessity. Jesus is not a footnote to Adam and his Fall; the Fall, and indeed creation itself, is a footnote to the purpose of God in Jesus Christ.
