Why is it that we have such a hard time controlling our tongues? Its such an important part of us, capable of doing great things, but it also can do the very worst things. Build people up or tear them down, praise God or curse Him... as well as countless other things.
We must be careful with our tongues. They are so important in our walk with God. We should be using them for positive things, not for wasting them with idol words.
Matthew 12:35-37 "A good person produces good things form the treasury of a good heart and evil person produces evil things from the treasury of an evil heart. And I tell you this, you must give an account on judgement day for every idle word you speak. The words you say will either acquit you or condemn you."
Don't be foolish and wasteful with your words. They are more important than we realize. Every day, notice the good things that people do. Uplift them. Train your tongue to speak the good things. Let go of the bad things, and don't let them come out of your mouth.
