One of the things that Christopher West likes to say at his live talks is worth repeating, because I personally think it's brilliant (especially to those who are not married or have visions of what married life will be like).
He starts off by telling the joke that there are 4 rings to marriage, 1 engagement ring, 2 wedding rings, and after that, the suffering. As the audience does a mix between laughter, and some shocked faces he normally says "I'm willing to bet that the married couples in the room are the ones who are not laughing right now."
He then goes onto add that anyone who thinks true love does not require true sacrafice does not understand what love is, and should get down on their knees and spend time contemplating the crucifix.
I know there are those that are appaled to hear a joke like that about marriage, but it is true, love requires sacrafice.
Peter, I do recall his "4 rings of marriage" as it made my former spouse very uncomfortable; he did NOT like the fourth ring (suffering) AT ALL. He didn't want to think that even for a minute he might have to "suffer" to make the marriage work. After the TOB talks from CW my former spouse and I talked several times about the "suffering" and there was no changing his mind. At the time I was in semi-denial about his bipolar diagnosis and did not realize that he was already suffering tremendously from untreated bipolar. He couldn't deal with anymore "suffering"; the suffering he was experiencing from his untreated bipolar illness was already more than he could handle.
CW has lots of good things to say in TOB, BUT I still say he is an opportunist. There isn't anything morally wrong with being an opportunist, unless they are causing people to stray from the truth.
