God's "Yes" and "No" to Humanity

Good stuff from Stephen Nichols:

I know it is summer time, but here is a quiz. It’s only one question and it’s fill in the blank. Ready? Christology is by nature bound up with the doctrine of _________ ?

This sentence comes from lectures given by Dietrich Bonhoeffer at the University of Berlin in 1932. After that year, the Nazis would rise to power in Germany. Bonhoeffer would lose his license to teach and eventually become the director of one of five underground seminaries to serve the Confessing Church—a church that rose up against the German Lutheran Church, which had embraced and endorsed the Nazi party.

Now back to the quiz. Here’s Bonhoeffer’s answer: “Christology is by nature bound up with the doctrine of justification.” This sentence comes from his lectures on twentieth-century systematic theology. He began the last lecture, which he entitled, “Preaching,” with a simple but urgent and ultimate question, “What should we preach?” We must preach Christ, he declares. Preaching Christ means nothing other than preaching the gospel. Preaching the gospel means, and only can mean, preaching the doctrine of justification.

Pulling a page from Luther’s playbook, Bonhoeffer speaks of how the cross is God’s “No” to humanity and to any attempt to achieve salvation, to attain righteousness. The cross slams the door on any and all attempts to merit salvation, to merit God’s grace. The cross is also simultaneously God’s “Yes” to us. Through his active and passive obedience, Christ has achieved for us what we could not. Christ died for the penalty of sin, enduring God’s wrath. Christ fully kept the law as the perfectly obedient Son. At the cross, Christ both undid what Adam had done and did what Adam could not do. “This is the reason,” Bonhoeffer says, “for the cross.” We have no hope without it.
