Look at why the Prophets came... and with that in mind, why are we fighting?

Look how Abraham strove to bring faith and love among the people; how Moses tried to unite the people by sound laws; how the Lord Christ suffered unto death to bring the light of love and truth into a darkened world; how Muhammad sought to bring unity and peace between the various uncivilized tribes among whom he dwelt. And last of all, Baha’u’llah has suffered forty years for the same cause--the single noble purpose of spreading love among the children of men--and for the peace and unity of the world the Bab gave up his life.
