False teachers may use manipulative tactics to gain followers, such as twisting scripture to fit their own agenda or focusing on material gain. They may also claim to have exclusive knowledge or authority, and discourage questioning or independent thinking. False teachers may also exhibit immoral behavior or teach doctrines that contradict the core beliefs of Christianity. It's important to be vigilant and discerning, and to seek guidance from trusted mentors and the Bible when evaluating a teacher's teachings and actions.
