God gave everyone an internal moral thermostat, the conscience. The word means “con-science” in the Latin or “co-knowledge. It is one of the means of grace that teaches us how to change. Along with the Spirit of God, the Word of God, and the people of God, our consciences assist us in the transformation process. Of course, a miscalibrated conscience will not do this, choosing instead to be our worst enemy. So I want to discuss this essential responsibility of training the conscience.
