In the sermon, each idea is either explained, proved, or applied. It may be a story to be told or a subject to be completed to clarify or amplify. State a proposition to be proved. Define important terms in language the audience understands, because a mist in the pulpit becomes a fog in the pew. Give the implications of the biblical principle to be applied.
Theological truth is useless until it is obeyed.
The purpose behind all doctrine is to secure moral action. Always write the conclusion with the purpose of the sermon in mind. The purpose states the reason why the author wrote this and what you expect to happen in the life of the hearer as a result of preaching this sermon. A sermon is not to be like a firecracker to be fired off for the noise it makes. It is a hunter's gun, and at every discharge he should look to see his game fall.
