In his book Making Sense of God, Tim Keller notes that when the national anthem is sung at sporting events, the cheering begins on the line “o’er the land of the free.” The singer quite often extends that line with a lengthy high note. Keller writes, “Even though the song goes on to talk about ‘the brave,’ this is an afterthought. Both the melody line and our culture highlight freedom as the main theme and value of our society.”

But true love imposes limits on our obsession on freedom. The film Secondhand Lions captures this well. In a scene near the end of the film, a small fatherless boy who has been abandoned by his mother to be raised by his crazy great-uncles. The boy tells one of his uncles, who is prone to depression and has contemplated taking his own life, that he cannot do that because he, the small boy, needs him. “You're my uncle. I need you to stick around and be my uncle.” The faithfulness of love will shape—and constrain—the freedom of love.
