There were Shepherds keeping watch over their flocks by night.

Faithful to the task, God was faithful to announce to them, first. Who is on earth? The only Peace that there is on earth is in Christ. He was here and the angels were rejoicing. Peace is on earth, they kept saying. How come, only the shepherds could hear them shouting? Peace is on earth! Jesus is born. God is walking on the earth in human flesh. The angels carried their exaltation from heaven where it dwells in God's presence to the earth where He was. Alot of people missed it. Not the shepherds on watch that night. They heard the joyful sound and got to be among the first to worship Him. Halleluia!
