This was an excellent foundation to our marriage. Built on foundations described in the Bible, following the tenents in this series has helped us stay out of trouble.
I've noticed that most of the advice on here pertains to guys alone. The woman has a part in the marriage too. She's supposed to respect her husband unconditionally. The man is supposed to love her unconditionally, a sacrificial love, "as Christ so loved the church."
It's worked out wonderfully for my wife and I, and you don't really need to be a Christian to take the advice to heart.
