“God is not some distant ruler, as in Deism, but is deeply personal. God knows all the details of Mack's life, of his terrible loss; and Papa explains that she was there, accompanying Mack, even at the hardest moments of his life. This, observed Bishop Barron, is the God of the Bible, the God of Psalm 139:
O Lord, you have searched me and known me.
You know when I sit down and when I rise up;
you discern my thoughts from far away.
You search out my path and my lying down,
and are acquainted with all my ways.
Even before a word is on my tongue,
O Lord, you know it completely.
That is the God, says Bishop Barron, who is portrayed very effectively in this book. And isn't the goal of the spiritual life to be ‘friends’ with God?”
