Proverbs 4:23 & 24, “Above all else, guard your heart, for everything you do flows from it. Keep your mouth free of perversity; keep corrupt talk far from your lips.”
I can’t say this is totally true for everyone, but I have seen it in my own life… if I want to cut down on the less civil words and responses in my life, I need to watch what I watch. I’m a Netflix addict, a movie fiend, and sometimes I’m not the wisest of watchers.
Jesus will echo this Proverb’s sentiment in his own ministry when speaking of purity in Luke 6:43-45, “Out of the overflow of the heart the mouth speaks.” When I was a kid I heard it expressed as the axiom, “Garbage in, garbage out.” I was warned that if I filled up on the wrong stuff, the wrong stuff would come back up on me. Harsh words. Inappropriate words. Quick anger. Misplaced priorities. It’s all there and way too easy to pack too much in.
I need to choose the best source material. I need the best in to have the best out. I need to plan ahead for my civility by guarding the source.
