The Gospel According to Johnny Cash | I Walk the Line

Johnny Cash sang "I walk the line" as a promise to his wife that he would be faithful to her when he was on the road. It was a promise he would have a hard time keeping. We, too, have a hard time keeping our promises — whether to each other or to God. We sin repeatedly in big and small ways. When we mess up, is it possible to out-sin God's grace? What does God think of us when we break our promises? These questions are considered in the second installment of The Gospel According to Johnny Cash.
