House and Porch Analogy
The point: Don't try to force the introduction, particularly in consecutive expository preaching; often, it must be left until the end of preparation.
The sermon is like a house, and the introduction is the porch. You must know the house's structure before building the porch, lest it be unsuitable or misplaced, illustrating the need to develop the sermon's substance before its introduction.
Now, let me explain what I mean and why I've made that general guideline. Since the sermon is the house, you better know where your house is and the general structure of the house before you build your porch. You might have a nice little porch sitting out in the middle of your backyard. Or, to change the analogy, you might have a porch suitable for an old antebellum mansion, but not at all suitable for a little Cape Cod in Pequonic.
