I listened to a message from this website this morning. It was recorded on 10-1-2006 and was by Gary Rosberg about marriages in America today:

Alot of it was informative, but non-applicable. There were a few parts that stood out, though. Near the end he mentioned three things to look for in a potential spouse (my ears perked up).
1. A teachable heart
2. A broken heart
3. A forgiving heart
Near the beginning he talked about your marital status being your witness, and he targeted Christian couples.
A good message.
