Every good message has two things: an effective beginning and a well-defined ending.
Too many speakers and presenters just wander into a message. A little bit of this, a little bit of that. Or worse, they stick an irrelevant introduction onto their speech or sermon because they like it, not because it fits. The introduction should point to where the message is going in a clear, concise, and compelling fashion.
If the introduction is getting the message in the air, on the back end of the message is a good landing. It’s sighting the runway and knowing when to bring down the plane. Many great speeches lose their impact because the speaker starts circling the runway, unsure of how to end the message. Lose the ending and there’s a good chance you’ll lose the impact.
Alpha and omega, beginning and end.
