What does Jude say about the nature of false teachers?

In Jude, false teachers are described using vivid metaphors that highlight their lack of substance and danger to the faith. They are likened to clouds without water—bringing false hope without delivering the nourishing truth—and trees that bear no fruit, indicating a lack of spiritual growth and vitality. These descriptions signify their deceptive nature; they appear to provide guidance but lead others astray. Understanding these characteristics helps Christians discern harmful teachings and reinforces the necessity of adhering to the true Gospel and the saving work of Jesus Christ.
