A sharp tongue is a sinful tongue.
Those who rattle off get-back answers and love to render verbal justice are also those who tend to be without empathy and have never learned to respond to the Holy Spirit when dealing with ungodly aggression.
Soldier of The Cross, it is the flesh that wants to shoot back. It is always a false balance.
We are to return good for evil. Sometimes that means being silent and other times the Lord will give a word that reveals His deep work in the heart.
Most folks grow up with the habit of answering back. The Soldier of The Cross may not live this way.
It is what comes out of the mouth that defiles a man.
Only He can make the deep changes.
Dedicate your faculties to Him regularly.
Aloud.
