The apostle Peter’s counsel is appropriate for both young and adult Christians. He said: “Always [be] ready to make a defense before everyone that demands of you a reason for the hope in you, but doing so together with a mild temper and deep respect.” (1 Peter 3:15) What does it take to be ready to make such a defense? First, you must understand what the Scriptures teach. To take a stand at school on matters such as nationalism, politics, drug abuse, or morals, you must first understand the reason for the Christian stand and must sincerely believe in it.
For example, the apostle Paul told fellow Christians: “Do not be misled. Bad associations spoil useful habits.” (1 Corinthians 15:33) Do you agree with that? As Paul indicated, it is easy to be misled in the matter of association. A person may appear friendly and agreeable. But if he does not share your concern for Jehovah’s service or even believe in the Bible’s promises, he is a bad associate. Why? Because his life is based on different principles, and things that are very important to a Christian may be of little consequence to him.
This is not surprising, for Jesus said of his followers: “They are no part of the world, just as I am no part of the world.” (John 17:16) It is impossible for a person to be a true Christian and at the same time be a part of this world, of which Satan is the god. (2 Corinthians 4:4) Do you see how such a separation from the world protects a Christian from the corruption and strife that plague so many today? If so, then you can understand why you must maintain your separateness, even if this means that you cannot join in some school activities.
