A friend of mine carries a badge. He told me that he is not concerned about being pulled over for his driving now. He just makes sure that his badge is in plain view of the officer pulling him over. If you did not know that he is now carrying a badge, you might be concerned about his driving record. Jesus did not come to abolish the law, but to fulfill it. By His grace, we have forgiveness of our sins. However, we are to strive not to sin. We are to be an example of Christ to others.
Romans 6:15 (ESV)
15 What then? Are we to sin because we are not under law but under grace? By no means!
