Just as a rotten tree produces bad fruit, false religion produces people who do bad things. The world is full of trouble because of the bad things people do. There is immorality, fighting, stealing, oppression, murder, and rape. Many who do these bad things have a religion, but their religion does not move them to practice what is good. They cannot be God’s friends unless they stop doing bad things.—Matthew 7:17, 18. We must wage spiritual warfare in this Christian walk with Christ!
