The nuclear submarine Thresher had heavy steel bulkheads and heavy steel armor, so it could dive deep and withstand the pressure of the ocean. Unfortunately, on a test run in 1963, the Thresher's nuclear engine quit, and it could not get back to the surface. It sank deeper and deeper into the ocean. The pressure became immense. The heavy steel bulkheads buckled; the Thresher was crushed with 129 people inside.

The Navy searched for the Thresher with a research craft that was much stronger than submarines. It was shaped like a steel ball and was lowered into the ocean on a cable. They finally located the Thresher at a depth of 8,400 feet: one and a half miles down. It was crushed like an egg shell. That was not a surprise, for the pressure at that depth is tremendous—3,600 pounds per square inch.

What was surprising to the searchers was that they saw fish at that great depth. And these fish did not have inches of steel to protect them. They appeared to have normal skin, a fraction of an inch thick. How can these fish survive under all that pressure? How come they are not crushed by the weight of the water? They have a secret. Their secret is that they have the same pressure inside themselves as they have on the outside. Survival under pressure.

John assures us, "The one who is in you is greater than the one who is in the world." We will be victorious in the battle against Satan because Jesus poured his Spirit into our hearts. "You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world."
