Rabbi Sacks was one of the world\u2019s deepest thinkers on religion and the challenges of modern life. He died last week after a short battle with cancer. When Krista spoke with him in 2010, he modeled a life-giving, imagination-opening faithfulness to what some might see as contradictory callings: How to be true to one\u2019s own convictions while also honoring the sacred and civilizational calling to shared life \u2014 indeed, to love the stranger?
