Wow. This is convicting! How often have I said things that are not nice about others? How often have I gossiped? How often have I said things on social media that should not have been said? No matter how often I determine to do better, something still flies out of my mouth, or my fingers (social media) that shouldn't.
It is true, no man can tame the tongue or the fingers that type what they shouldn't or the pen that writes what it should not. It all comes from the heart. The heart is the issue and these things are only windows to the heart. My dad says, "Even a fool is considered wise when he holds his tongue." There much wisdom in that.
Even a fool is counted wise when he holds his peace; When he shuts his lips, he is considered perceptive. (Proverbs 17:28 NKJV)
