Read Luke 12:49-56
49 “I came to set the earth on fire, and how I wish it were already kindled! 50I have a baptism to receive, and how distressed I am until it is over! 51Do you suppose that I came to bring peace to the world? No, not peace, but division. 52From now on a family of five will be divided, three against two and two against three. 53Fathers will be against their sons, and sons against their fathers; mothers will be against their daughters, and daughters against their mothers; mothers-in-law will be against their daughters-in-law, and daughters-in-law against their mothers-in-law.”
54 Jesus said also to the people, “When you see a cloud coming up in the west, at once you say that it is going to rain—and it does. 55And when you feel the south wind blowing, you say that it is going to get hot—and it does. 56Hypocrites! You can look at the earth and the sky and predict the weather; why, then, don’t you know the meaning of this present time?
Jesus expresses frustration at the people's failure to recognize who he is. Recognizing who he is they will take a stand. That stand will cause conflict (within and without).
