Illuminating Devices

layers Part 5 of 9 lightbulb 20 illustrations in this sermon

Pastor Albert N. Martin expounds on the fifth axiom of preaching: the necessity of legitimate and judicious "illuminating devices" in the proclamation, explanation, and application of scriptural truths. He argues for their desirability based on a God-given law of learning, the scriptural mode of preaching exemplified by prophets, Christ, and apostles, and the history of effective preaching. Martin then details the primary function of these devices as clarifying truth, and secondary functions such as gaining attention, making surprise attacks on the conscience, making sermons interesting, and aiding memory, while also providing warnings and suggestions for cultivating their use.

Key Quotes

“The proclamation, explanation, and application of scriptural truths, aided by legitimate and, the word judicious you'll find written in, legitimate and judicious illuminating devices, must be our constant labor.”
“If the sermon has as its raw materials the thick, reinforced concrete of biblical truth, then these devices are the windows in the structure which let in light and make the construction pleasant.”
“Some things may be so clear in themselves that to illustrate them is to insult the intelligence of your listeners and to lose their goodwill.”
“The preacher who ignores it ignores it not only to his own peril as a preacher, but he robs his hearers of the benefit of what otherwise might be effective proclamation of the Word of God.”
“They were so possessed by the truth and so convinced that the man in the pew is not so much impressed by accurate philosophical statement as he is by vivid imagery, by these legitimate and judicious illuminating devices that they threw themselves into preaching in such a way that these devices were scattered throughout their ministries to the profit of their hearers.”
“Reasons are the pillars of the fabric of a sermon, but similitudes are the windows which give the best lights.”
“It's truth that we want our people to grasp. It's truth that we want our people to feel.”
“Truth has enough of its own inherent offensiveness. Let's not make it doubly offensive by dull, lifeless, unilluminated sermonic exercises that are like elephants plodding through the jungle, knocking down trees that are in their paths.”

Applications

All listeners

  • Always seek to honor the God of general revelation when handling the sacred realities of special revelation.
  • Any commitment that our people understand the truth of God will find us laboring to use legitimate and judicious illuminating devices.
  • When deciding on illustrations, ask: 'What decision will best serve the interest of truth?'
  • Let your soul burn with disinterested love for your people, and let your mind and spirit be permeated with the truth, to guide the judicious and legitimate use of devices.
  • If you get a glassy stare from your audience, pray for and actively seek an imagery, analogy, or illustration on your feet to clarify the truth.
  • Seek to know how to make surprise attacks upon the consciences of men by the judicious use of these devices.
  • Do not overload the sermon with any of these devices; spending too much time on stories profanes the sacred office.
  • Don't ever use these devices for their own sake, such as telling a joke just to prove you're a nice guy.
  • Do not use them unless they clarify truth to the average hearer; avoid obscure references.
  • Don't ever use them for mere filler.
  • Seek to employ illuminating devices in ordinary conversation to make preaching more natural.
  • Labor at using these devices in the instruction of your children, especially during family worship.
  • Sustain much general reading (biographies, theology, church history) as a means of impression and acquisition of illustrative material.
  • Expose yourself to and analyze living models of preaching, even those with whom you disagree theologically, to learn effective communication.
  • When a sermon is fairly well formed, go over it and note places where devices are most needed, thinking as a listener.
  • Analyze statements that could be made more interesting, clear, or forceful with the use of these devices.
  • Labor at cultivating the use of illuminating devices constantly, giving yourself wholly to these things for manifest progress.
