The Fourth Sunday in Advent, especially if we are in Series B of the lectionary, is a Sunday that has special memories for me. Nine years ago my dad was planning to preach a sermon on the Gospel text Luke 1:26-38. But God had different plans for him on that Fourth Sunday in Advent. God was calling him home to be with Him.
The sermon was never preached, although it had been written. Over the years I’ve read and reread that sermon. This sermon wasn’t intended to be a “farewell”. Yet, it has provided me comfort then, as it still does today.
As my dad reflected on the message the angel Gabriel gave to Mary, he wrote:
It is truly wonderful. God would become flesh. This “Son of the Most High” would deliver us from the power of sin, death, and the devil, and give to us a kingdom that is forever. Though King Herod would try to kill this baby Jesus, he would live that he might suffer and die for the whole world. May our hearts praise God as those of old did. God be praised for giving us a Savior.
I think my dad would have gladly joined in on that Advent Sunday with these words of Paul & Ruth Manz.
Rejoice in heaven all ye that dwell therein, Rejoice on earth ye saints below, For Christ is coming, is coming soon, For Christ is coming soon!
E’en so, Lord Jesus, quickly come, And night shall be no more; They need no light nor lamp nor sun, For Christ will be their All!
I have just started reading 
Take for example this last Sunday – The Baptism of Our Lord. The “official” Hymn of the Day from Lutheran Service Book was Luther’s wonderful baptism / catechism hymn “To Jordan Came the Christ, Our Lord” (LSB 406/407). How many of our Lutheran congregations sang this hymn? My congregation didn’t, but they did get to hear an organ prelude by Zachau.
