Where there is mystery, there must be faith. Faith, you cannot change no matter how you look at it. Either you have it, or you don't. For us, it is very simple because our feet are on the ground. We have more of the living reality. There was a time when the Church had to show majesty and greatness. But today, people have found that it does not pay. They have found the emptiness of all that pomp so they are coming down more to the ground, and in coming down there is the danger that they are not finding their proper place.
God has created all things. All butterflies, the animals—the whole of nature He has created for us. To them God has not given the will power to choose. They have only an instinct. Animals can be very lovable and love very beautifully, but that is our of instinct. But the human being can choose.
That is the one thing that God does not take from us. The will power, the power to will. I want to go to heaven and I will, with the grace of God. If I choose to commit sin, that is my choice. God cannot force me to do otherwise. That's why when we become religious we give up that will power. That is why the sacrifice is so great: the vow of obedience is very difficult. Because in making that vow you surrender the only thing that is your own—your will power. Otherwise my health, my body, my eyes, my everything are all His and He can take them. I can fall, I can break, but my will power doesn't go like this. I must choose to give it and that is beautiful.
