Psalm 133. This short song describes the goodness and pleasantness of brothers and sisters living together.  Although modern life places obstacles in the path of spending time together, the development of Christian community is essential to our growth as Christians and our mission of making disciples by praising, learning, and loving.  The Jews probably sang this song as they went up to Jerusalem for the annual feasts, but the images of the psalm emphasize that the blessings of unity and eternal life flow down from God.
