Question: "How should Christians stand up for their faith in such an anti-Christian world?"
Answer: As Christians, the two things we can do to stand up for Christ are to live according to His Word and grow our own knowledge of Him. Christ said, “let your light shine before men…” (Matthew 5:16). This means that we should live and act in a way that supports the Gospel. We should also arm ourselves with knowledge, both of the Gospel (Ephesians 6:10-17) and of the world around us. 1 Peter 3:15 says: “But in your hearts set apart Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect.” All we can do is live and teach as Christ would and let Him take care of the rest.
Critics of Christianity have become more and more vocal recently. This is partly because there are many people who do not believe in God or understand the truth about Him at all. Yet, the apparent swell in anti-Christians is also due to perception. As with many topics, those who truly despise Christianity are the loudest and most vocal of the non-believers. The vast majority of those who do not believe don’t really care enough to bother believers. The few angry, vocal, bitter unbelievers make enough noise to seem more numerous than they are.
The typical insult from the non-religious crowd is to refer to believers as “ignorant,” “stupid,” “brainwashed,” or otherwise suggest that those who have faith are less intelligent than those who do not. When a Christian puts up a good fight by standing up intelligently for his faith, the terms change to “bigot,” “extremist,” or “zealot.” When people who know that believer is kind and loving hear this, the loud-mouthed atheist starts to look like the fool that he or she is (Psalm 53:1). Most non-believers have not had personal reasons to see Christians negatively, but they sometimes hear so much from the loud anti-Christians that they just assume it is so. They need examples of Christ-like living to see the truth.
Of course, when someone claiming to be a Christian says or does something that is not Christlike, the angry, loud crowd is there to point them out as a typical religious hypocrite. This is something we have been warned to expect (Romans 1:28-30; Matthew 5:11). The best thing to do is to point out a passage of the Bible that speaks against what the person did. For example, a murderer is violating Exodus 20:13. Point out that just because a person says they are a Christian, and even if they think they are a Christian, does not mean that they are. Matthew 7:16,20 tell us that true Christians will be known by their actions, not merely by their profession. And, remind them that absolutely no one lives without sinning at all (Romans 3:23).
The important thing to remember is that no one, no matter how persuasive, can force anyone to believe anything they don’t want to believe. No matter what the evidence, no matter what the argument, people will believe what they want to believe (Luke 12:54-56). This is true for both sides, since the angry antiChristian types are some of the least tolerant people around. But conviction is not a Christian’s job. The Holy Spirit convicts people (John 14:16-17), and they choose whether or not to believe. What we can do is present ourselves in a way that is as Christ-like as possible. Most of the “beating up” that Christianity endures involves actions that are not in line with Biblical teachings, or arguments that are deliberately twisted. It is sad that there are many atheists who have read the entire Bible, word for word, looking for ammunition to throw at Christians, and that there are many Christians who have hardly read the Bible at all.
It’s hard for the angry crowd to accuse a Christian of being a hateful, cruel bigot when that person demonstrates a life of kindness, humility, and compassion. When a Christian can discuss, debate or debunk secular arguments accurately, the label of “ignorant” no longer fits. A Christian who has read the arguments of the secular crowd, and can politely point out their flaws, helps to deflate the stereotype pushed by the vocal atheists. Knowledge is the weapon, and it is invincible when we let Christ direct us in how to use it.
