If your wife agrees to say the traditional wedding vows of: "Will you obey him, and serve him, love, honor, and keep him in sickness and in health? And forsaking all others keep yourself only to him, so long as you both shall live?"
If your fiancee agrees to these wedding vows, your marriage will last. If she doesn't agree to those vows, your wedding won't last. It's simple stuff.
Yes. It basically makes it clear we are to honor and respect our husbands, as long as they cherish and respect us.
