We come now to one of the most serious and penetrating parts of the Sermon on the Mount—Matthew 7:21–27. In this passage, Jesus shifts our focus to the core of the matter: the unavoidable choice each of us must make. Earlier, in verses 13 and 14, He described two gates—one narrow, one broad. The narrow gate leads to life, while the broad one leads to destruction. We must choose. Not choosing is itself a decision, and Jesus urges us to understand the weight of our response to Him.
This sermon is filled with contrasts: two ways, two trees, two kinds of people, and here, two foundations. Each picture calls for a personal decision. Jesus is not merely offering suggestions—He is presenting a clear, unavoidable invitation: choose life. He is the Initiator, and we are the responders. He extends grace and truth, but we must answer with faith and obedience.
But what does it mean to truly follow Christ? What does it mean to reject Him, whether by outright denial or passive indifference? Jesus helps us understand the difference through a sobering warning. In verses 21 to 23, He speaks of the danger of a verbal profession—saying the right words, even using His name, but lacking true submission and obedience. Then in verses 24 to 27, He warns of the danger of intellectual knowledge—hearing His words but failing to live them out.
In both cases, the problem is the same: a life that hears or speaks but does not do. A heart that acknowledges Christ in name or theory, but not in action or truth.
False Prophets and False Professors
Earlier in this chapter (verses 15–20), Jesus warned us to watch out for false prophets. These are people who appear spiritual but lead others astray. They are deceptive—wolves in sheep’s clothing. How can we discern the difference between what is true and what is false? Jesus gives us three criteria: the character and conduct of the person, the content of their teaching, and the impact of their influence. Just as a tree is known by its fruit, a person’s life will reveal their true nature in time.
But Jesus doesn’t stop with teachers—He now turns to the listeners. It’s not only the leaders who can be false. Some of us, though not teaching others, may still be deceived ourselves. Jesus moves from false prophets to false professors—those who claim to follow Him but do not actually know Him.
In Matthew 7:21–23, He gives a startling statement: “Not everyone who says to Me, ‘Lord, Lord,’ will enter the kingdom of heaven.” These are people who outwardly honor Him. They may even do impressive works—prophesying, casting out demons, performing miracles. Yet Jesus says, “I never knew you. Depart from Me, you who practice lawlessness.”
