AOL/Huffington features a column by one Tim Suttle, encouraging evangelicals to embrace the Lenten fast/sacrifice as a way to check the experience of "satiation," restoring a sense of dependence on God.
Fair enough and common enough, that's Lewis's point restated. We give it a B+. It's true and has value but misses the imperative opportunity.
We continue to offer this challenge, differently expressed yet again:
The follower of Jesus who understands the cross as demanding that one give one's life for the sake of others will constantly have her tendency to satiation checked by stepping out to risk serving another. That makes Lenten fasts redundant.
Maybe the church at large is frustrated with the shallow discipleship of the church in our age (and ages past) because we keep constructing shallow proxies for genuine discipleship.
