Have you ever felt like the world rushes on around you and doesn't even notice you are there? The things you say - people don't hear them. The things you do - people don't see them. It's as if you don't exist, and all you are engaged in is a waste of time and effort? Such a life would be miserable and in desperate need of Jesus Christ! But sadly many Christians feel this way about their spiritual lives. All they say and do doesn't make much difference. The world seems utterly oblivious. Reasonably, those who feel this way become discouraged and lethargic.
"The Loudest Sermon": considers a lesson so striking and clear that even those farthest from the Truth will notice and know that we are true disciples of Jesus Christ, possessing a treasure not held by any other class of man.
