Your unsaved, relatives, friends, coworkers, neighbors, etc., do not care what you believe, if your life does not show the reality of Jesus Christ, His love and character in all the areas of your life. If you say that Jesus Christ is your Lord and Savior, they expect you to act, respond, live as He would and they do not expect you to compromise with sin and their behavior. When you do, they do not take serious your profession nor see any reason that they should surrender their lives to Christ. Therefore, you actually help them on their way to Hell and you will have to give an account for that to your Lord. It is a very serious matter when we live in such a way that people do not see Jesus Christ in us. Our walk does count far more than our talk!
