The following may actually be four points in a presentation, or they may be treated very quickly as the last point of a sermon. But more generally, this is a foundational outline for the basic moral reasoning and argument that lies at the heart of the application.

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.”
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.”
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.”
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…”

a) In every text of the Scripture there is somehow a moral principle. It may grow out of because of what it shows us about the character of God or Christ, or out of either the good or bad example of characters in the text, or because of explicit commands, promises, and warnings. This moral principle must be distilled clearly.

b) But then a crisis is created in the hearers as the preacher shows that his moral principle creates insurmountable problems. The sermon shows how this practical and moral obligation is impossible to meet. The hearers are led to a seemingly dead end.

c) Then a hidden door opens and light comes in. The sermon moves both into worship and into Christ-application when it shows how only Jesus Christ has fulfilled this. If the text is a narrative, you can show how Christ is the ultimate example of a particular character. If the text is didactic, you can show how Christ is the ultimate embodiment of the principle.

d) Finally, we show how our inability to live as we ought stems from our rejection of Christ as the Way, Truth, and Life (or whatever the theme is). The sermon points out how to repent and rejoice in Christ in such a way that we can live as we ought.
