Theirs Is the Kingdom of Heaven | Matthew 5:1-20

Matthew 5 is introduced with a warning most people don’t expect: the Sermon on the Mount is not meant to make people feel safe in themselves. It’s meant to leave people astonished, exposed, and emptied. When Jesus finishes, the crowds aren’t comforted—they’re stunned, because He teaches with authority, not like the scribes. And the sermon doesn’t wrap up with a soft landing. It ends with a dividing line: hear and do these words and you’re a wise man on the rock; hear and ignore them and you’re a fool building on sand. That’s because Jesus is not handing out moral tips. He’s taking a wrecking ball to self-righteousness. The man who thinks he’s fine because he hasn’t murdered anyone gets cut down: anger, contempt, and “you fool” put a person in danger of hell-fire. The man who thinks he’s clean because he hasn’t committed adultery gets cut down: lust is adultery in the heart. The religious man who prays, gives, and fasts gets cut down: if it’s done to be seen by men, it profits nothing—he already has his reward. So the Sermon on the Mount drives people into poverty—not financial poverty, but poverty of spirit. It leaves them asking the question that shows up later in Matthew: who then can be saved? That’s exactly what happens with the rich young ruler. He comes asking what good thing he must do to inherit eternal life, and Jesus presses him until the truth shows: he’s not “good,” and he won’t surrender what owns his heart. He walks away sorrowful, and the disciples don’t respond with smug relief. They respond with shock: then salvation is impossible. And that’s the point. The sermon is designed to destroy the lie that people can balance good deeds against bad deeds and earn acceptance—like a spiritual scale where morality can outweigh sin. That’s not biblical theology. The Bible says everyone is a sinner, everyone has offended an infinitely holy God, and no one has anything in themselves to recommend them to Him. So the Sermon on the Mount does something merciful and severe: it leaves people empty-handed. It brings them to the throne of grace not with confidence in performance, but with open hands begging for mercy. And that’s why the most hopeful line in the entire sermon is the first one: “Blessed are the poor in spirit, for theirs is the kingdom of heaven.” The kingdom doesn’t belong to the impressive. It belongs to the broken. Do you want to support Church of The Word? https://cotwstl.org/give/ Check out our church here! https://cotwstl.org/ #biblestudy #faith
