The Sermon on the Mount
5:1 Seeing the crowds, he went up on the mountain, and when he sat down, his disciples came to him.
2 And he opened his mouth and taught them, saying:
3 “Blessed are the poor in spirit, for theirs is the kingdom of heaven.
4 “Blessed are those who mourn, for they shall be comforted.
5 “Blessed are the meek, for they shall inherit the earth.
6 “Blessed are those who hunger and thirst for righteousness, for they shall be satisfied.
7 “Blessed are the merciful, for they shall receive mercy.
8 “Blessed are the pure in heart, for they shall see God.
9 “Blessed are the peacemakers, for they shall be called sons of God.
10 “Blessed are those who are persecuted for righteousness’ sake, for theirs is the kingdom of heaven.
11 “Blessed are you when others revile you and persecute you and utter all kinds of evil against you falsely on my account. 12 Rejoice and be glad, for your reward is great in heaven, for so they persecuted the prophets who were before you.
In the Sermon on the Mount Jesus tells his disciples that the change to come in the Kingdom begins today with a change in their hearts. The Beatitudes declare that the path to true and unending happiness starts when the Gospel changes everything.
