The cost of non-discipleship

You know those "helpful" little summaries you often find at the beginning of a Bible passage? "The Question of Baptism"; "Bread of Life Discourse" and so on? Well, the Gospel today usually appears in Bibles with a header inspired by Bonhoeffer: "The Cost of Discipleship." And it is that: "If you want to be my disciple, take up your cross." But the passage could just as easily be headed "The Cost of non-discipleship." After all, "the one who seeks his life will lose it.... what profit does anyone show who gains the whole world but loses his own life?" It's a good commentary on yesterday's harsh "Get behind me, Satan!" directed to Peter: Follow me!
