A) If God is omnipotent, can He make a rock so heavy that He can't lift it?
B) What happens when the irresistible force meets the immovable object?
Answers: A) No. B) Nothing.
If something is all-powerful, then the query is meaningless. Therefore God cannot be all-powerful, since both states cannot exist at once. God can be the most-powerful being of all, but that's not the same. He can make a rock Superman can't lift, which is not a small deal.
Ditto the force versus the object. If one exists, then by definition, the other cannot. So there's never going to be a meeting of the twain. The qualifiers have to come out. "Almost," "nearly," "pretty close ..."
In chess, I was taught to play as if my opponent would never make a mistake, to shoot for the perfect game; however, if you have two players of equal skill and neither makes a mistake, white always wins. White moves first, and if he never missteps, black is always one move behind.
Playing as if the opponent won't screw up means that you play your game and don't depend on him to give it to you.
In football (American style) both the defensive lineman and offensive lineman covering the same position cannot do their job on a given play; somebody has to get beaten for the game to proceed. They can trade back and forth, play by play, but they can't both prevail at the same time. Somebody has to fail for any game to go forward.
In our art, we are taught certain principles and how to do certain moves. If I am doing that, accomplishing what I set out to accomplish, then it doesn't matter what you are doing. I will be covering my lines, engaging my targets, using my tools, and unless your goal is to get flattened, you won't be getting what you want.
Not to say that I can pull this off every time. There's the theory versus the practice. But that, like playing the chess guy who isn't going to make a mistake, is the goal. This is why we say that the three most important things in a fight are the same as the most important things in a small business:
Location, location, and location. If I have a place to stand, my lever handy, you will get moved.
