Fire on the Earth
Luke 12:49-53
49 “I came to throw fire on the earth. I wish it were already kindled. · WEB
The most agitated words in the Gospel: a fire he wants lit, a baptism he dreads, and division through the middle of a family.
"I came to throw fire on the earth. I wish it were already kindled" Luke 12:49.
These five verses are this Gospel's alone and they are unlike anything around them. The composure that runs through the book breaks for a moment, and what shows is urgency and distress together.
Fire in Scripture purifies and destroys, and John had promised a baptism in the Holy Spirit and fire in the same breath as a threshing floor Luke 3:16–17. Both senses are live. What is unmistakable is that he wants it started — I wish it were already kindled is the sentence of a man impatient with the interval.
"But I have a baptism to be baptized with, and how distressed I am until it is accomplished!" Luke 12:50.
The fire waits on something. He speaks of a baptism still ahead of him, though he was baptized in chapter three, so the word is being used of an immersion of a different kind — going under something that closes over a person. It is the same image he offers the sons of Zebedee when they ask for thrones Mark 10:38.
And the word for his state is strong: hemmed in, pressed, held under constraint. He is not calm about it. This is the same voice that will pray in a garden for the cup to pass Luke 22:42, and it is worth noticing that the distress is not confined to the last night. He carried it up the road.
Until it is accomplished is the word used on the mountain for the departure he would accomplish at Jerusalem Luke 9:31 and on the cross when it is finished. What is dreaded is also what is being walked toward.
"Do you think that I have come to give peace on the earth? I tell you, no, but rather division" Luke 12:51.
The question is asked because everyone would have answered it wrongly, and this book most of all — angels sang about peace on earth over his birth Luke 2:14, and Zechariah's song ended with feet guided into the way of peace Luke 1:79.
Both are true and neither cancels the other. What he brings is peace with God, and the effect of it in a world that does not want it is division. Peace and unanimity are not the same thing, and a message that leaves everyone comfortable has not been understood by anyone.
"From now on, there will be five in one house divided, three against two, and two against three" Luke 12:52.
The fracture line runs through a household rather than between nations, and the pairs are named: father and son, mother and daughter, mother-in-law and daughter-in-law Luke 12:53. The words are the prophet's, describing a society coming apart Micah 7:6.
It is a sober thing to put beside the invitations of this Gospel, and it belongs there. He is not warning that following him may cost a family; he is saying it will divide one, and telling people so in advance.
