Now it is interesting to observe that this particular Beatitude follows immediately the reference to the peacemakers. In a since it is because the Christian is a peacemaker that he is persecuted. What a wealth of insight and understanding this gives us into the nature of the Christian life! I do not think you will ever find the biblical doctrines of sin and the world put more perfectly anywhere in Scripture than in just these two Beatitudes — “Blessed are the peacemakers,” and “Blessed are they which are persecuted for righteousness’ sake.” If a Christian man is a peacemaker this is what happens to him.
