Only if you believe that these statements are outrageous do you have a chance for that state of inner strength and transparency, which I would think is the mark of real sainthood. Persevering through inevitable change is another mark. You won't be a candidate for sainthood, it seems to me, if you deny that change will ever take place, or construct your life as such a fortress that you never admit it. Instead, saints know that things will change. They regard the fact of change itself as something precious, something that comes, and they admit that change has a high cost.
Real change seems to come over time.
It is hard won. It is the accumulation of actual experience, and the reaction or reflection on that experience. Real saints don't reduce life to a moral crusade. So often real saints, like everyone else, resolve to do better. They know that the resolve to do better usually fails, and the outcome can be discouraging.
