In the movie The Poseidon Adventure, the ocean liner S.S. Poseidon is on the open sea when it hits a huge storm. A wall of water crashes through the ballroom chandelier. Men in tuxes and women in evening gowns scream and run. Lights go out, smoke pours into rooms and, amid all the confusion, the ship flips over.

Because of the air trapped inside the ocean liner, it floats upside down. But in the confusion, the passengers can't figure out what's going on. They scramble to get out, mostly by climbing the steps to the top deck. The problem is, the top deck is now 100 feet under water. In trying to get to the top of the ship, they drown.

The only survivors are the few who do what doesn't make sense. They do the opposite of what everyone else is doing and descend into the dark belly of the ship until they reach the hull. By going down, they reach the ocean's surface. Rescuers hear them banging and cut them free.

In marriage, it's as if God has turned the ship over and the only way for us to find freedom is to choose what doesn't make sense: lay down our lives by serving, supporting, and sacrificing for our spouses.
