And there may be more times when I shall want you to trust when you cannot, and may not, and must not yet understand. But the time will come when your trust shall be whole and complete in me, and when you shall understand as though the sunlight himself shone through. Then you shall bless me from first to last for your own sake, and for the sake of others, and for her dear sake to whom I swore to protect.”
