Advent is a season both for contemplating and for imitating the sharp-eyed men and women of Scripture. Not those whose eyesight would have tested 20/20, but all those ancestors in faith who kept their eyes open, looking for the coming of the Lord. Some, like the Old Testament prophets, scanned the horizon for signs of the Messiah who would reveal God's glory. Others had the spiritual vision to recognize and receive that Messiah when he came as a vulnerable infant in a manger.
