The saying, "Try it, you'll like it" is especially bad. If Satan is a snake, then "trying out" sinful behavior is like playing with baby snakes. The Bible calls Satan an "ancient serpent" and "a liar ... from the beginning". Young people can try to tempt their peers to try vices such as drinking or cigarette smoking in defiance of parents. "It won't hurt you," they say. But what they don't tell you is that alcohol and nicotine are addictive (see addiction). You can't stop merely because you decide to stop.
