A joy that is shared is a joy made double. (John Roy, musician)

I bring you good news that will bring great joy to all people. The Savior . . .  the Lord—has been born today in Bethlehem . . . When the angels had returned to heaven, the shepherds said to each other, “Let’s go to . . . see this thing that has happened … After seeing him, the shepherds told everyone what had happened and what the angel had said to them about this child, Luke 2:10-17.

Always be full of joy in the Lord. I say it again—rejoice! (Philippians 4:4)
