Here's the deal Fellow Humans -- don't say anything you don't want repeated. And don't say anything about others you wouldn't want to be said about you. The one to complain to is God. He can handle anything and He will also change your heart if you are totally honest with Him. If there is someone really making you mad go talk to that person. If you aren't willing to work it out with them, then you should just be quiet about it.
Our words are powerful -- death and life are in the power of the tongue. If you aren't building up, you're tearing down. It is one or the other.
Jesus says the one who isn't gathering with me is scattering. Be a gatherer. Be an encourager. Be a builder.
