Sadly, it seems that John's life had hit a rough patch the past year or so as he had lost his job and was looking for work. I can't help but wonder if in some way the stress might have contributed to his untimely passing.
Perhaps we can take away from this that even living through a rough patch is still LIVING. The value of a person's existence is not diminished by his professional/financial setbacks. It can be hard to maintain sight of that when going through such a time.
