“Few things are more important in a home than its conversation, and yet there are few things to which less thought is given. The power of communication, which lies in the tongue, is simply incalculable.” ~J.R. Miller, Homemaking
Not that your conversation ought to be flowers and roses all the time. I don't think that's what he us trying to say here. :-)
Isn't it interesting that often times we're more careful about how we speak to each other when in the company of folks outside the home? And yet the people at home are the ones we love and are bonded to the most! How deeply important words are. They can have a huge impact on a person's day, for good or for bad. How vitally important encouraging words are to the home-life. And it all starts in your thoughts.
“Finally, brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, dwell on these things.”
If you are "dwelling on these things," it will come out in your attitude toward your family. If you are thinking of the honorable things, the lovely things, and the excellent things about your husband, kids, siblings, and parents, there is no room for negative talk. Not that there is never a time for correction in their lives. We know that not one of us is perfect, and there will always be occasional re-direction needed.
But nagging your husband, or any family member about a negative character trait will most often do nothing but harm, while encouragement and praise in positive character growth can do wonders.
