“The face of sin today often wears the Halloween mask of tolerance. Do not be deceived. Behind that facade is heartache, unhappiness, and pain. You know what is right and what is wrong, and no disguise, however appealing, can change that truth. The character of transgression remains the same. If your so called friends urge you to do anything you know to be wrong, you be the one to make a stand for right, even if you stand alone. Have the moral courage to be a light for others to follow. There’s no friendship more valuable than your own clear conscience, your own moral cleanliness…”
