Matthew 5:1–12 contains the beautiful Beatitudes delivered by Jesus in His Sermon on the Mount. The series of nine sentences describes an unlikely group of people as blessed: the poor in spirit, those who mourn, the meek, those hungry for righteousness, and the merciful. All are blessed because of their part in the kingdom of heaven. This includes those persecuted for the sake of righteousness and on account of Jesus. Instead of despairing, they should rejoice for the great rewards they will receive in heaven. These are not prerequisites for salvation; instead, they are the natural expressions of saving faith in the life of those who know Christ.
