Do you need a guard?

Psalm 141:3 “Set a guard over my mouth, O Lord; keep watch over the door of my lips.” The responsibility of a guard is to provide safety and security. Parts of our own bodies can generate danger and become our own enemy.  Not only can our mouths hurt ourselves, our words can hurt others even to such a degree that a person can be hurt for life.  Spouses, parents, friends or someone unfamiliar can be hurt or can cause hurt and that hurt might very slowly heal or never heal.  Let us be very careful with the words we speak.
