The plot to moral reasoning

In his excellent lectures on preaching, Tim Keller gives his basic outline for preaching to the heart as well as to behaviour. In fact, he describes it as the foundational outline for all the moral reasoning and argument that lies at the heart of application.

a. The Plot winds up: WHAT YOU MUST DO.

• "This is what you have to do! Here is what the text/narrative tells us that we must do or what we must be."

b. The Plot thickens: WHY YOU CAN'T DO IT.

• "But you can't do it! Here are all the reasons that you will never become like this just by trying very hard."

c. The Plot resolves: HOW HE DID IT.

• "But there's One who did. Perfectly. Wholly. Jesus the---. He has done this for us, in our place."

d. The Plot winds down: HOW, THROUGH HIM, YOU CAN DO IT.

• "Our failure to do it is due to our functional rejection of what he did. Remembering him frees our heart so we can change like this ..."

(From the lecture notes here)

We're all preachers, not least to our own hearts, so it is important to think how we apply the Bible to our hearts. This structure is biblical, Christ-centred and packed with grace where it matters. But it is important that it is also a story. This makes it interesting to hear because there's dramatic tension and it is effective because it also takes the Christian on a journey from death to life, law to Gospel and self to Christ. We all want to make that journey, and by starting with the command, and not Christ, you don't just preach the goal but how to get there.

That's why I love the distinction between law and Gospel. It is about a movement. It's not an exercise in chopping up scripture but a dynamic.
