I thought the following article by John Piper was very perceptive and challenging. Here's a flavor:
What kind of Christians do we want our churches to breed? Consider: Apathetic Christians, who spend most of their discretionary time in worldly entertainment, seldom pray, weep, or work for the reaching of the perishing peoples of the world. Do not coddle them. Confront them. Tell them to get a life. PG13 videos every other night leaves them spiritually powerless and empty. They need a cause big enough to live for. And die for.
The article is an introduction to Desiring God's upcoming fall conference: Finish the Mission.
Some of you might think of attending. I think it could be quite stirring and helpful.
