Gary A. Anderson (From ‘Charity: The Place of the Poor in the Biblical Tradition’)

My wife was once in charge of a swimming class for adults that included a number of individuals who had had near-drowning experiences in their younger years. This naturally led to an extraordinary fear of the water. Now, anyone who has done a proper investigation of the physics of water knows that the human body is buoyant enough to float quite naturally on its surface. But in order to exploit this fact, you have to be relaxed, and, in turn, must trust the capacity of water to hold your body afloat… Knowing something and acting on that knowledge are often two quite different things.
