I showed this video to my marriage and family class the other day and I thought it was too good not to share with all of you. If you haven't read The Meaning of Marriage, run (don't walk) to get it right now. Or go to Amazon and buy it immediately. It is worth it. A lot of what the Kellers say in this video is from their book, but I particularly loved how Tim Keller talked about the basis for relational intimacy in marriage. But don't just take it from me, listen to the whole thing (and get the book!).
