Charisma Magazine (not recommended) interviewed Francis Chan last year on the publication of his new marriage book, "You and Me Forever".
Here is the trailer with Chan and his wife Lisa announcing the book. It is not a long trailer, just 2 minutes or so. If you watch it, perhaps something will strike you, like it did me. I'm sure there are many things that may strike you, but I'm thinking of one particular thing that jumped out at me.
Let me know what you think in the comments. After a while I'll put my answer in the comments, depending on response.
