Though I do not agree with the "read a verse of Scripture and depart never to return" style of teaching/preaching, I did learn to be practical when I speak. This has helped me not only in preaching and teaching, but also in my everyday business life.
It takes actual studying to be able to deliver truth in a practical package. You may have to understand it yourself, first. I agree that the ability to speak plainly and practically, and stay focused on only the necessary elements in a short meeting, is golden. I am grateful to Bro.Hyles for that.
