The Bible doesn't address Muslim violence because Islam began centuries after the Bible was written. Though the Qur'an contains some violent teachings, we cannot assume that all Muslims agree with or are even familiar with those. The Bible teaches that we should treat others, even unbelievers, respectfully, which includes avoiding stereotyping them. Genesis indicates that all people are God's image-bearers (Genesis 1:27). That gives all people inherent value, including Muslims. Scripture teaches that believers are never to compromise the truth (1 Peter 3:15; Jude 3) and that we're to treat others respectfully (1 Peter 2:12). Our conduct toward others, including Muslims, may be the very example that brings them to the truth.
People love categorizing. We rely on it for food shopping (produce first, meats, dairy, etc.). We sort our closets and drawers by clothes for work, gym, summer, winter (skinny and . . . not). We might even sort our podcasts by category (e.g., travel, music, talk).
But we shouldn't sort people into categories of violent, nice, stingy, generous, and more. We should base our view of each person on our interaction with that person. Too often, though, rather than doing that, we're influenced by negative impressions from media.
But no matter how different people seem, we all have one thing in common: We're made in God's image. Christians respect others based on that commonality. When we treat others with respect and kindness, we help dispel the stereotype that media often put onto Christians (judgmental, dogmatic, ignorant). Even more important, we glorify God through our treatment of others, pointing them to Him who loves His creation and desires that they come to the truth of Christ.
