Over the course of human history, countless sermons have been preached, but the greatest sermon of all was delivered by the greatest preacher—Jesus Christ. His Sermon on the Mount was revolutionary, challenging the cultural and religious expectations of His listeners. As Jesus nears the conclusion of His sermon, He issues a stark warning about a danger that has plagued the church from the beginning—false prophets. Unlike external threats, this danger arises from within the church. Satan attacks both from the outside through persecution and from the inside through deception. Jesus calls His followers to be on high alert, for these counterfeit prophets masquerade as true messengers of God while leading people away from the truth.
