Let your speech always be with grace, as though seasoned with salt, so that you will know how you should respond to each person. (Colossians 4:6 NASV)

The story is told of two polite people who were having dinner together. On the table there was a dish with one big piece of fish and one small piece of fish.
They politely said to each other: "You may choose first."
"No, you may choose first."
This went on for a while. Then the first person said, "OK, I'll take first." And he took the BIG piece of fish.
The second person said, "Why did you take the big piece? That's not polite!"
The first person said, "Which piece would YOU have taken?"
The second person replied, "Why, I would have taken the SMALL piece, of course."
The first person said, "Well, that's what you have now!"

The New Collegiate Dictionary defines a polite person as someone who is "marked by an appearance of consideration, tact, deference, or courtesy."

The quality of politeness is one which seems to be disappearing in our society. As I grew up, I was taught to say, "Yes, ma'am," and "Yes, sir." These terms are not often heard from young people today. Even the words "please" and "thank you" are not used as often as they should be.

Some might say that politeness is just "a small thing." They are correct. Politeness is "a small thing," but that doesn't mean it is an insignificant thing. Politeness is a lot like salt — you don't always pay attention to it when it is present, but it is very obvious that something is lacking when it is absent.

Of all people, Christians should be most polite, because politeness is a characteristic of agape — genuine Christian love.

Politeness is a characteristic of genuine Christian love.
Remind the believers to ... be ready to do good, to speak no evil about anyone, to live in peace, and to be gentle and polite to all people. (Titus 3:1-2 NCV)

[Love] does not behave rudely. (I Corinthians 13:5a)

Make an effort today to see that the love you show to others around you includes the quality of politeness.
