I found these summaries from the Lutheran Church Missouri Synod that are designed to help prepare us for the coming Sunday.  Of course, I found them and then saved them to my desktop, but did not change the name of the file so I did not remember that I had them until last night.

The passage in Zephaniah is one of my favorites.  I can sing it!

THIRD SUNDAY IN ADVENT

Zephaniah 3:14–20
Philippians 4:4–7
Luke 7:18–35

The Coming of Jesus Enables Us to Rejoice

The Third Sunday in Advent has traditionally been called by the Latin word, Gaudete, meaning “Rejoice!” For as you are called to repentance, so also are you also urged to rejoice in the coming of the Lord Jesus Christ. By His own Cross, He has accomplished salvation for you; “He has cleared away your enemies,” “taken away the judgments against you,” and has come to reign in your midst. Indeed, He rejoices over you with gladness! (Zephaniah 3:15­–17). Therefore, even from prison St. Paul encourages us to “rejoice in the Lord always,” knowing that the peace of God will guard and keep us in Christ Jesus (Philippians 4:4, 7). We find an example and encouragement in the case of John the Baptizer. As he languishes in prison, he calls upon Jesus and is strengthened by the Word of the Gospel that he receives. The same good news is preached to you, by which all things are made new and even “the dead are raised up” (Luke 7:22). Do not be offended by the cross, therefore, but let your life be one of prayer and thanksgiving (Luke 7:23; Philippians 4:6).
