John Piper, a well known preacher and writer, took a sabbatical for the last eight months. In the following post he gives an update on that sabbatical. I admire his wisdom and humility in his comments on marriage about half way down the post.  Just goes to show how all of us, no matter how long we are married or how well we know scripture, need to intentionally keep working on our  marriages – even if there is no major crisis.
