The word peace in the Gospel according to Luke is a big word. This was the First Sunday in Advent and the gospel lesson is often the triumphal entry or Palm Sunday. The theological theme of the that text is the Kingship of Jesus. No different in Luke, but Luke adds this strange cry from the crowd leading Jesus into Jerusalem. “Blessed is the King who comes in the name of the Lord! Peace in heaven and glory in the highest! (Luk 19:38 ESV)” Did you catch the strange word? Peace in Heaven. The entire phrase is an echo of the Angels at Christmas, but instead of peace on earth, now it is peace in heaven. And if you do the word study, roughly midway through Luke you find this, “Do you think that I have come to give peace on earth? No, I tell you, but rather division. (Luk 12:51 ESV)”
The peace of God is not a generic peace. The Angels were never singing just “peace on earth”. They sang “on earth peace among those with whom he is pleased! (Luk 2:14 ESV)” The specific peace is the Kingdom of God, the Lordship of Jesus Christ. The specific peace is one imposed…through grace. You can take it or you can leave it, but you can’t work for it. You can’t earn the peace. The Father just declared it. The war was over on the cross.
The only question is our response. Do we accept the peace, or continue an insurgent war. Which Kingdom do we choose, the Kingdom of this World, or the Kingdom of Heaven. The tyrant Satan or the humble Christ. Choose your prince.
