(Proverbs 21:23 KJV) Whoso keepeth his mouth and his tongue keepeth his soul from troubles.
Usually we “keepeth” (guard NASB) (8104) focus on exterior threats. We drive defensively. We lock our doors. We keep our valuables in a safe. That doesn’t seem to be the focus in this verse. Here the danger is from within.
Don’t get it confused. We may make excuses that someone got us so stirred up that we said what we didn’t intend. They may have stirred the pot but we are the ones who refused to take it off the fire.
We can control what we say but not if we wait until the last minute. A guard is useless if you only get one after the break-in. Locking the door won’t work unless you do it every night. These safety measures are habits and habits develop from conscious choices over time.
So? Get started. Get a handle on it. Start laying the ground work. Look at the verse again. The consequences involve eternity not just our day.
