Around us, we can sometimes see people getting their joy and grief mingled by their words, or some others getting disgraced or making social problems by mistakes in words. Like it says, "a soft answer turned away wrath", one word can hurt ones heart or give joy. Therefore it is never too much to stress the importance of words. All the time we should be aware of the fact that one without a mistake in words is a perfect person, and we should make others happy with good and beautiful words. "Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen." (Ephe. 4:29)
