49 I am come to send fire on the earth; and what will I, if it be already kindled? 50 But I have a baptism to be baptized with; and how am I straitened till it be accomplished! 51 Suppose ye that I am come to give peace on earth? I tell you, Nay; but rather division: 52 For from henceforth there shall be five in one house divided, three against two, and two against three. 53 The father shall be divided against the son, and the son against the father; the mother against the daughter, and the daughter against the mother; the mother in law against her daughter in law, and the daughter in law against her mother in law. (Luke 12:49-53 KJV)
Not Peace, but Division
Jesus then spoke of his own coming sufferings and those of his followers (Luke 12:49). “I came to send fire on the earth.” Some understand this fire as the gospel and the Spirit’s work—refining, purifying, consuming sin like fire. The gospel was being preached, and the Spirit was beginning to work—Christ baptized with the Holy Spirit and fire (Acts 2). But, based on the context, this fire seems to refer to the fire of persecution. Christ is not the author of persecution as sin, but he permits it and uses it as a refining trial for his followers. The fire was already kindled in the growing hostility of the Jews toward Christ and his disciples.
“What will I if it is already kindled?” In other words, if persecution is already breaking out, what should I say? Shall I try to stop it? No. It must affect me and all who follow me, and it will bring glory to God.
Christ himself would suffer first (Luke 12:50): “I have a baptism to be baptized with.” His sufferings are pictured as both fire and water (Psalm 66:12; Psalm 69:1-2). He would be overwhelmed by both. He calls his suffering a baptism, not a deluge. He would be dipped in them, not drowned, and he refers to them in a sacred way. His suffering was a form of consecration; by it he offered himself for God’s glory (Hebrews 7:27-28).
He faced his sufferings with determination: “How distressed I am until it is accomplished!” Like a woman in labor, he longed to endure the pain to bring forth the joy of salvation. His sufferings were the travail of his soul, which he welcomed for the redemption of humankind (Isaiah 53:10-11).
Then he told his followers that they too must expect hardship (Luke 12:51): “Do you suppose that I came to bring peace on earth?”
They likely expected that the gospel would bring peace and be received by all, perhaps thinking it would lead to outward prosperity and unity. The Old Testament spoke of peace in the Messiah’s kingdom, which they interpreted as external peace.
But Christ warned that they were mistaken. The actual result of the gospel would be division—not because it intends to divide, but because many resist it. Though the gospel promotes unity and love, those who reject it will oppose those who accept it. The preaching of the gospel disrupts false peace and challenges long-standing errors. When Satan ruled the Gentile world, all was quiet. Philosophers and idolaters got along. But the gospel brought a shaking (Ezekiel 37:7). When some believed and turned from darkness to light, others reacted with hostility. Even among believers, differing opinions on minor matters would lead to division—but God allows it to teach mutual forbearance (1 Corinthians 11:18; Romans 14:1-2).
This division would even affect families (Luke 12:53). Fathers and sons, mothers and daughters would be divided when one turned to Christ and the other did not. The believing one would try to win the other (1 Corinthians 7:16), while the unbeliever would feel judged and respond with hatred or even persecution. Religious hostility can override natural affection, just as Jesus said (Matthew 10:35). In the book of Acts, the gospel often provoked persecution. Wherever it spread, there was resistance, conflict, and slander. Therefore, Christ’s disciples should not expect peace on earth. They are sent out like sheep among wolves.
