Having studied a particularly non-three point chunk of exciting engaging narrative from Esther 4-7 today with one of my Staff that's a helpful thought.
Application ought to be the pointed driving home of the gospel. It is the lively and repeated application of the Word to the heart of the congregation to the end that it might be believed. It is not the derivation of principles which can then be turned into moral instruction. Application is the Spirit’s work of awakening faith in the Christ who we proclaim.
