The Beatitudes
Jesus begins the Sermon on the Mount by pronouncing blessings on those who embody the values of the Kingdom of Heaven, such as the poor in spirit, those who mourn, the meek, and the peacemakers.
The Beatitudes reveal the upside-down nature of God's Kingdom, where the humble and persecuted are blessed. They emphasize the inner qualities and attitudes that are valued by God.
The Beatitudes echo Old Testament themes of God's favor on the humble and oppressed (e.g., Isaiah 61:1-3) and set the stage for the ethical teachings of Jesus that follow.
