The Sermon on the Mount is a Manifesto where Jesus is giving us a glimpse of the kingdom of God, not the kingdom of this world that the people of Israel have been picturing for thousands of years, and giving us an invitation to live in alignment with the kingdom of God.
He kicks the whole Sermon on the Mount of with what is referred to as the Beatitudes where Jesus makes 8 statements about those who are “blessed.”
“’Blessed are the poor in spirit, for theirs is the kingdom of heaven. “Blessed are those who mourn, for they shall be comforted. “Blessed are the meek, for they shall inherit the earth. “Blessed are those who hunger and thirst for righteousness, for they shall be satisfied. “Blessed are the merciful, for they shall receive mercy. “Blessed are the pure in heart, for they shall see God. “Blessed are the peacemakers, for they shall be called sons of God. “Blessed are those who are persecuted for righteousness’ sake, for theirs is the kingdom of heaven.'” – Matthew 5:3-10 ESV
