Quite a bit different from a college class in philosophy or ethics, isn't it? It sounds more like Paul's "boxing against the air" metaphor. Or James, "show me your faith by your works."
Frankly, we could use more of that in the church. I think they used to call it discipleship back in the day. But, we can't have that, can we? No dying to self for us! No sirree! Live your best life now!
Only problem with that attitude is that the best life is one that is united with Christ—and his sufferings, his emptying himself.
Kenosis. Cruciformity. Theosis.
Good words, all of them. And necessary. May we learn to live them!
