"...We are never to think of God's power in terms of what he could conceivably do by the exercise of what we may call sheer omnipotence which crushes all obstacles in its path. We are always to think of God's power in terms of his purpose. If what he did by sheer omnipotence defeated his purpose, then, however startling and impressive, it would be an expression of weakness, not of power. Indeed, a good definition of power is "ability to achieve purpose. This applies to the power of a gun, or a drug, or an argument, or even a sermon! Does it achieve its end? Does it fulfill its purpose?
We must realize that God's power is not put forward to get certain things done, but to get them done in a certain way, and with certain results in the lives of those who do them. We can see this clearly in human illustrations. My purpose in doing a crossword puzzle is not to fill in certain words. I could fill them in easily by waiting for tomorrow morning's paper. Filling them in without the answers is harder but much more satisfying, for it calls out resourcefulness, ingenuity, and discipline which by the easier way would find no self expression.
