34. However great and unutterable all this is, that is still greater and more wonderful in comparison, that the human heart has been enabled to believe it all. That must indeed be a great heart which can embrace more than heaven and earth can hold. Hence it must be evident what a great, sublime and divine power and work faith is, which can do that which it is impossible for nature and all the world to do, and it is therefore no less a wonder than all the other miracles and works of God. It is even more wonderful than that God became man, born of a virgin, as St. Bernhard says. These things, as we have heard, namely the love of the Giver and of him who was given, and the unworthiness of the recipient, placed side by side, are incomparable as to greatness. On the one hand everything is so great, and on the other, man’s heart is so small and narrow and weak that the in-finiteness of difference is startling and amazing.
