It would be well to keep this in mind, because, quite often in the daily unfolding of our Christian life it happens that we fight the wrong battle, if one may put it that way, because we orient our efforts in the wrong direction. We fight on a terrain where the devil subtly drags us and can vanquish us, instead of fighting on the real battlefield, where, on the contrary, by the grace of God, we are always certain of victory. And this is one of the great secrets of spiritual combat to avoid fighting the wrong battle, to know how to discern, despite the ruses of our adversary, which is the real battlefield, what we truly have to struggle against and where we must place our efforts.
