Who is your #1 critic? Who is the person who never seems to have anything nice to say (or think) about you? Who is the one who always notices your mistakes and never acknowledges your successes? Who seems intent on tearing you down at every turn, belittling you in front of others and then (metaphorically) kicking you while you’re down?
How should you respond? The easy (and sometimes “auto-pilot”) response is to go on the attack. Or, sometimes just doing nothing and saying nothing seems the course to take. But, God calls upon us to “do” more than nothing. He calls upon us to “do good” (which would include “saying 
good”) unto them (Luke 6:33-35; Rom. 12:20-21; Gal. 6:10). In other words, “turn the tables.” Find opportunities to compliment them and say nice things. “Nice shoes. Nice tie. Nice car.” “Good job on the project. Good job in that situation. Nicely handled.” “Thank you for pointing that out to me. I appreciate that.” “Have a nice day.” Remember that every critic, every enemy and every hateful person has a soul who needs Jesus!
