In his book Sermon on the Mount: A Foundation for Understanding, author and professor Robert A. Guelich writes of the role Christ-followers play as peacemakers:

The peace intended is not merely that of political and economic stability, as in the Greco-Roman world, but peace in the Old Testament inclusive sense of wholeness, all that constitutes well-being…

The "peacemakers," therefore, are not simply those who bring peace between two conflicting parties, but those actively at work making peace, bringing about wholeness and well-being among the alienated.
