My husband and I listened to an online sermon recently which contained a story I had never heard before.

The USS Thresher was a nuclear-powered submarine that sank in 1963, killing all 129 people on board. A series of events caused it to sink and then to implode due to the extreme pressure deep in the ocean.

Research equipment with cameras that could withstand the oceanic pressure were lowered and found the Thresher in five pieces.

It's hard to fathom water pressure strong enough to crush a submarine.

Yet there are fish and creatures that live at such depths. How are they not crushed?

This article tells of some features of a few specific deep-sea creatures. But the bottom line, Wikipedia says, is "Deep-sea organisms have the same pressure within their bodies as is exerted on them from the outside, so they are not crushed by the extreme pressure."

The fish and other creatures aren't crushed by deep sea pressure because their internal pressure is equal to it. In fact, many die (even explode) when they are brought to the surface for study because their pressure is no longer equalized.

We face a lot of pressures these days, don't we? Making a living, keeping up with responsibilities, making time for those we love. Then we all have struggles against our own besetting sins. The world is getting less friendly to Christianity every day. And we have an enemy of our souls who seeks our destruction like a roaring lion.

We're not equal to it in ourselves. "My flesh and my heart may fail," Asaph says. Mine, too. But he goes on to say, "but God is the strength of my heart and my portion forever" (Psalm 73:26).

"Little children, you are from God and have overcome them, for he who is in you is greater than he who is in the world" (1 John 4:4). The one within us is more than equal to the pressures around us.

"Now we have this treasure in clay jars, so that this extraordinary power may be from God and not from us. We are pressured in every way but not crushed; we are perplexed but not in despair" (2 Corinthians 4:7-8, HCSB).

Sometimes God relieves pressure by removing a burden from us. Other times, He gives us grace to bear it. He invites us to cast our care on Him, to depend on His strength in our weakness, to come to Him for rest.
