The teaching of Jesus in the Sermon on the Mount serves as a manifesto for Kingdom life, and the Beatitudes portray for us a Kingdom culture that is contrary to that of the world. These studies reveal to us an invasion of this world with a culture that defines a heavenly kingdom. The Kingdom of God is not a simply a far-off dream held by Christians. The Kingdom was established by Jesus Christ, and the culture of the Kingdom invades the world through the lives of God's people.
