From Pope Benedict XVI:
I express my certainty that God, despite the infinite difference between him and me, is such that I can speak to him, may even address him familiarly as “thou” (German du). His greatness does not overwhelm me, does not reject me as insignificant and unimportant.

Certainly I am subject to him as a child is subject to his father, yet there is such a fundamental similarity and likeness between him and me, yes, I am so important to him, I belong so closely to him, that I can rightly address him as “Father.”

My being born is not a mistake, then, but a grace. It is good to live even though I do not always perceive it. I am wanted; not a child of chance or necessity, but of choice and freedom.

Therefore I shall also have a purpose in life; there will always be a meaning for me, a task designed just for me, there is a conception of me that I can seek and find and fulfill. When the school of life becomes unbearably hard, when I would like to cry out as Job did, as the psalmist did — then I can transform this cry into the word “Father” and the cry will gradually become a word, a reminder to trust, because from the Father’s perspective it is clear that my distress, yes, my agony, is part of the greater love for which I give thanks.
