There are two ways of handling pressure. One is illustrated by a bathysphere, the miniature submarine used to explore the ocean in places so deep that the water pressure would crush a conventional submarine like an aluminum can. Bathyspheres compensate with plate steel several inches thick, which keeps the water out but also makes them heavy and hard to maneuver. Inside they're cramped.

When these craft descend to the ocean floor, however, they find they're not alone. When their lights are turned on and you look through the tiny, thick plate glass windows, what do you see? Fish! These fish cope with extreme pressure in an entirely different way. They don't build thick skins: they remain supple and free. They compensate for the outside pressure through equal and opposite pressure inside themselves. Christians, likewise, don't have to be hard and thick skinned--as long as they appropriate God's power within to equal the pressure without.
