Blessed are the peacemakers, for they shall be called the children of God.”
Peacemakers are people living with everyone in peace and harmony and fostering peace among people. When other people are at enmity among themselves they try to reconcile them, or at least pray to God for their reconciliation.
Peacemakers remember the words of the Saviour, Peace I leave with you, My peace I give unto you (John 14:27). It be possible, as much as lieth in you, live peaceably with all men, said the Apostle Paul (Romans 12:18).
To the peacemakers the Lord promises that they will be called sons of God. They will be the closest to God, heirs of God, joint-heirs with Christ. The peacemakers by their spiritual feat resemble the Only-begotten Son of God, Jesus Christ, Who came to earth to reconcile sinful people with Divine judgment and establish peace among people in place of the animosity reigning among them. Therefore to the peacemakers is promised the epithet, "sons of God," and inexpressible blessedness.
