what does the bible say?
In the Sermon on the Mount, Jesus opens with a series of statements concerning blessedness known as the Beatitudes. The seventh Beatitude is "Blessed are the peacemakers, for they shall be called sons of God" (Matthew 5:9). The Greek word translated "blessed" in this verse is one that is also translated "happy." A blessed person will have joy and contentment. Also, we must understand what a "peacemaker" is. The Greek word simply indicates a person who makes or works toward peace. A person can only work toward peace if he is at peace himself. Believers have peace with God through Jesus Christ (Romans 5:1). God is the source of peace (Philippians 4:7) and calls His followers to exhibit peace in their own lives (Romans 12:18; Galatians 5:22).
