The Sermon on the Mount is the great body of teaching given by Jesus in Matthew 5–7, delivered to His disciples and overheard by the crowds.
It sets forth the character, conduct, and righteousness of those who belong to the kingdom of heaven.
Far from lowering the law, Jesus intensifies its demands and locates true righteousness in the heart.
The sermon ends with a call to hear and obey His words, for only those who build on the rock will stand in the day of testing.
Early in His ministry Jesus went up on a mountain, sat down, and taught His disciples. The collection of sayings that follows is the longest continuous discourse recorded in the Gospels. It begins with the Beatitudes, which describe the blessedness of the poor in spirit, the meek, the merciful, and those who hunger for righteousness. Jesus then declares that He has not come to abolish the Law or the Prophets but to fulfill them, and He proceeds to show the true depth of the commandments against murder, adultery, oaths, retaliation, and hatred. He teaches on giving, prayer, and fasting, warns against anxiety and the love of money, forbids hypocritical judgment, and calls His hearers to enter by the narrow gate and to build their lives on His words. The sermon is not a new legal code for earning salvation; it is the description of life under the reign of God and the ethical demand that flows from belonging to the King. It exposes the inadequacy of outward religion and points to the need for a righteousness that only Christ Himself can provide.

The Sermon on the Mount is the King describing life in His kingdom. It is searching, demanding, and full of blessing. It exposes every heart that trusts in outward religion and calls for a righteousness that exceeds that of the scribes and Pharisees. No one can climb into the kingdom by these words; they are the life of those who have already been brought in by grace. The same Jesus who spoke them is the only One who perfectly lived them. He is the Rock on which the wise build. Hear His words. Do them. Build your life on the only foundation that will stand when the storms come. The crowds were astonished at His authority. Let the church still sit at His feet and live under His teaching — for of the increase of His government and of peace there will be no end.
