Worship or Emulation: Can we be biblical about this?

Just wanted to draw your attention to this article by John Piper. Whether within our local church or the universal, I'm confident we all need to think carefully and biblically about our reasons for putting others (or ourselves) forward as examples. So although this isn't about 1 Tim. 4:12, it's connected, as well as having other implications for sermon-listening, book-recommending, and blog-linking.
