Supporting people who spread false or harmful ideas makes you a partner in their work. The verse claims that even small acts of encouragement or hospitality can link you to the damage those ideas cause. The Greek word for "share" is koinōneō, which means to participate or have fellowship with—not just to agree, but to become involved. This challenges the belief that your actions are neutral if your intentions are good, or that you can stay uninvolved by being polite. Instead, it says that what you support or encourage matters, because it connects you to the outcome. For someone who wants to avoid conflict or who thinks it’s harmless to go along with things they don’t really believe, this verse is a warning. Sometimes, real integrity means refusing to support what’s wrong, even in subtle ways. It’s a call to think about the impact of your actions, not just your intentions.
