What types of faith are considered vain according to Scripture?

Scripture identifies several forms of vain faith, including the faith of devils, which acknowledges God but lacks any trust or obedience (James 2:19), and temporary faith that does not endure trials (Matthew 13:20-21). Historical faith acknowledges Jesus’ existence and works but lacks transformative belief, as many respect Jesus yet do not trust in Him for salvation. Furthermore, a faith that relies on human persuasion is equally vain, as true saving faith is upheld solely by the Holy Spirit's work. Recognizing these distinctions is vital in determining the authenticity of one's faith journey.
