If, then, you sometimes fail, do not lose heart, or cease striving to make progress, for even out of your fall God will bring good, just as a man selling an antidote will drink poison before he takes it in order to prove its power. If nothing else could show us what wretched creatures we are and what harm we do to ourselves by dissipating our desires, this war which goes on within us would be sufficient to do so and to lead us back to recollection. Can any evil be greater than the evil which we find in our own house? What hope can we have of being able to rest in other people's homes47 if we cannot rest in our own? For none of our friends and relatives are as near to us as our faculties, with which we have always to live, whether we like it or not, and yet our faculties seem to be making war upon us, as if they were resentful of the war made upon them by our vices. "Peace, peace," said the Lord, my sisters, and many a time He spoke words of peace to His Apostles.48 Believe me, unless we have peace, and strive for peace in our own home, we shall not find it in the homes of others. Let this war now cease. By the blood which Christ shed for us, I beg this of those who have not begun to enter within themselves; and those who have begun to do so must not allow such warfare to turn them back. They must realize that to fall a second time is worse than to fall once. They can see that it will lead them to ruin: let them place their trust, not in themselves, but in the mercy of God, and they will see how His Majesty can lead them on from one group of Mansions to another and set them on safe ground where these beasts cannot harass or hurt them, for He will place the beasts in their power and laugh them to scorn; and then they themselves -- even in this life, I mean -- will enjoy many more good things than they could ever desire.
