If you were to go down into the engine room of one of today's great ocean liners, you would discover a veritable marvel of engineering—machinery and equipment so huge and awesome, it boggles the mind. You would see tremendous gearboxes and levers and drive shafts that move the twin screws, which propel the ship through the ocean waves. However, although all of this machinery may be oiled and greased and ready to go, if you went into the boiler room and saw that the fire was out in the great boilers, you would soon discover why the ship was not moving across the ocean waves.
In this full-length sermon, Dr. Kennedy gives this picture to describe what much of the church of Christ is like today. The church is like a great ship. We are in the nave of that ship. It is a huge system. It has institutions and organizations and programs and ministries that even fifty-years ago were unheard of—even undreamed of. And yet, in many cases, it seems that the ship is making very little progress through the seas of this world.
Why is that? Dr. Kennedy says, to a large extent it is because "the fire is out in the furnace below," and revival is the great need of the church today.
