Okay, think on this: when we participate in negative self-talk, condemning ourselves; or if we participate in gossip, slander of others, we are doing the devil's work for the enemy.

"Summing it all up, friends, I'd say you'll do best by filling your minds and meditating on things true, noble, reputable, authentic, compelling, gracious—the best, not the worst; the beautiful, not the ugly; things to praise, not things to curse. Put into practice what you learned from me, what you heard and saw and realized. Do that, and God, who makes everything work together, will work you into his most excellent harmonies." Philippians 4:8-9, The Message
