What spurred this topic on was an episode of "Good Neighbors", a British show which has a man and wife deciding to leave the "rat race" and be self-sufficient. It is a very funny show. But one thing that interested me was in one episode where they have "transportation problems", i.e. no car. And their cart has just broken. So the wife, Barbara, decides to get a horse. The husband, Tom, says something like, "It's very sweet, but it's just not practical (or efficient, I forget which), is it?" He argues with Barbara, who sulks a little bit, but admits that Tom is right, and then life goes on as normal. Perhaps even more importantly, Barbara defends the decision to get rid of the horse over and against her dear neighbor, Mrs. Leadbetter, who tries to get Barbara to be "liberated." But Barbara is loyal to Tom, and defends the decisions he makes. It really is heart-warming to see a marriage on TV that works that well. In any case, most American women would have been rather offended that her husband argues with her, and comes right out with such a statement as, "It's just not practical, is it?"
Why do people ignore those verses I mentioned above? And please understand I am not excluding myself from all these accusations. The answer: the same old tired old reason people have been bitter, proud, angry, jealous, backbiting, etc. for millenia. People are sinful. They sin because they are sinners. And they need the gospel.
So let's say you are a Christian; you have the gospel. You should be one who is exceedingly difficult to offend. I find it helpful to think of things this way: if someone says something I don't like, it's either true or not. If it's true, then I need to change to become a better person; furthermore, this person might actually be trying to help me be a better person. Therefore, I should love them for that. If it's not true, then it has no hold over you. You can just let it wash over you. There's no need to dwell on it.
Of course, you will need God's grace to do this well; pray earnestly for it. This is part of your sanctification.
So next time someone says something you don't like, instead of thinking of suing them, you can lengthen your lifespan by not worrying about it unless it's true. Then you can lengthen your lifespan by following the advice.
