I have discovered that many readers of Christian blogs are people who are in particular need of fellowship because they are married to someone who does not share their faith.
If you are one of those readers, or if you are simply in need of some inspiration to keep going in the face of marital tension, I highly recommend listening to a talk by then-Bishop (later Archbishop) Fulton J. Sheen called "Marriage Problems." You can download it for free from the "Life Is Worth Living" page of the American Catholic Truth Society's site. The page is, incidentally, a real goldmine for Sheen fans, containing dozens of recorded instructions in the Faith, in high-quality audio.
