But then is the acquisition any benefit? Bonhoeffer remarked that it's a small wonder if the Gospel does not find a hearing under circumstances like that: "All our easy trafficking with the word of cheap grace simply bores the world to disgust, so that in the end it turns against those who try to force on it what it does not want." That expression goes pretty far in explaining the mess we're in today.
Jesus invited James and John, not to leapfrog to the throne, but to share his own cup, his own baptism. He offered them communion with himself. There's no greater grace possible in this life or the next. And those who accept that grace (no cheap grace!) really have a Gospel to proclaim.
