John Wesley emphasizes the profound teachings of Jesus in the Sermon on the Mount, particularly the blessings associated with purity of heart, peacemaking, and enduring persecution for righteousness' sake. He explains that true love for our neighbor must stem from a genuine love for God, and that the pure in heart will experience a deep connection with God. Wesley warns against the false teachings that focus solely on outward actions without addressing the heart's condition, urging believers to strive for inner holiness. He concludes by encouraging Christians to rejoice in persecution, as it signifies their alignment with Christ and the promise of eternal rewards.
