He answered with grave kindness, “I know it was hard for you to quite trust me then, for to trust such violence needs to understand, and I take it that you do not, that you cannot, trust me now, for you do not yet understand. 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.”
