For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. Just as the warriors put their hands on the Chief's little son as a sign that they accepted this little boy as their Peace Child, so we by faith receive Jesus into our lives to show that we are at peace with God. The difference in the stories is that God's Peace Child lives forever. If the chief had not given his son the tribes would have kept fighting and warriors would keep on dying.
Death is the wages that sin pays.
Peace with God is not something that we earn through our good deeds. It is a gift that we freely receive. Peace among those tribes in Irian Jaya was bought by the gift of the Peace Child. Each warrior indicated his willingness to receive the gift by placing his hands on the peace child. I do not give to you as the world gives.
