Why did Jesus say he came to create division?

The simple answer is that Jesus is unlike any other religious philosopher, he isn't about attonement as they say, he is about social justice and non-compliance with psychopaths, that's why he said I believe (don't actually know if he said it): thou drink their blood or their tears? Because as a fact in every society there's an abusive government in power that drinks your blood, an opposition that drinks your tears, and you are caught in the middle. Jesus shows a third way, the way of salvation from this system, the way of freedom, equality, and he shows us a method, to reject the system and its inherent corruption. My new favourite Jesus quote is " Luke 12:49-59 Do you think I have come to bring peace to the earth? No, I have come to divide people against each other!"

Jesus Christ was prophesizing the severe punishment Israel was going to face which happened during Jewish Wars (66-70 AD).

The generation of Jews during the time of Jesus was extremely evil.

We see Jesus calling them "wicked (or sinful) and adulterous generation." (Matthew 12:39, Matthew 16:4, Mark 8:38, etc.). We also see Jesus calling people in that generation that their father is devil (John 8:44) due to their evil nature. We also see Both Jesus Christ and John the Baptist calling them "offspring of vipers" (Matthew 23, Luke 3).

Even Jewish Priest Josephus agrees with Jesus on the wickedness of that generation.

"I shall therefore speak my mind here at once briefly: — that neither did any other city suffer such miseries, nor did any age ever breed a generation more fruitful in wickedness than this was, from the beginning of the world." (Jewish Wars V, 10:5).

We all know that Jesus Christ came to forgive those who repent. But Jesus Christ also came to judge those who didn't repent.

Luke 12:51-53 can also be read in Matthew 10:34-36.

Matthew 10:34-36 (NIV) - "Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword. For I have come to turn “‘a man against his father, a daughter against her mother, a daughter-in-law against her mother-in-law— a man’s enemies will be the members of his own household."

"A man's enemies will be the members of his own household" - This can also be read when Jesus Christ prophesized about the destruction of the city of Jerusalem and the city of temple of Jerusalem in Mark 13, Luke 21.

Mark 13:12-13 (NIV) - "Brother will betray brother to death, and a father his child. Children will rebel against their parents and have them put to death. Everyone will hate you because of me, but the one who stands firm to the end will be saved."

Luke 21:16-19 (NIV) - "You will be betrayed even by parents, brothers and sisters, relatives and friends, and they will put some of you to death. Everyone will hate you because of me. But not a hair of your head will perish. Stand firm, and you will win life."

He is speaking about division between believers and unbelievers , even between family members. Matthew 10:34-38 cross references the Luke account and gives a little more detail:

Matthew 10:34-38 (KJV)

34 Think not that I am come to send peace on earth: I came not to send peace, but a sword.

35 For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law.

36 And a man's foes shall be they of his own household.

37 He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me.

38 And he that taketh not his cross, and followeth after me, is not worthy of me.

The sword represents his Word "which is sharper than any two edged sword piercing even to the dividing asunder of soul and spirit , and of joints and marrow, and is a discerner of the thoughts and intents of the heart" ( Hebrews 4:12). Those that didn't believe would be against, and even persecute, the believers. For example, a newly believing son or daughter in a family of faithful Hebrew people who followed the law and rejected Yahuwshuwa ( Jesus) would cause problems and arguments. Same as Greek believers among their pagan families. Or in more modern times in a Muslim family. This causes division and huge problems even today. Even causing beatings, kicking them out, or even death. The prophets also spoke of these things to come:

Isaiah 19:2 And I will set the Egyptians against the Egyptians: and they shall fight every one against his brother, and every one against his neighbour; city against city, and kingdom against kingdom.

Micah 7:6 For the son dishonoureth the father, the daughter riseth up against her mother, the daughter in law against her mother in law; a man's enemies are the men of his own house.

lets look at some manifestations of this division in the scripture:

John 9:16 Because of this, some of the Pharisees said, "This man is not from God, for He does not keep the Sabbath." But others said, "How can a sinful man perform such signs?" And there was division among them.

John 10:19 Again there was division among the Jews because of Jesus' message.

Matthew 10:21 Brother will betray brother to death, and a father his child; children will rise against their parents and have them put to death.

John 7:43 So there was a division among the people because of him

Acts 14:4 But the multitude of the city was divided: and part held with the Jews, and part with the apostles.

Mark 13:13 And ye shall be hated of all men for my name's sake: but he that shall endure unto the end, the same shall be saved.

So the scriptures make it very clear that the coming of the Messiah caused great division between believers and unbelievers. Many believers were even martyred because of this.

I've often wondered about this passage. I currently read it less as a mission statement and more of a prophetic warning about religious conflicts that will arise as a result of some people accepting Christianity and others rejecting it. Jesus is warning his followers that following Him will not be easy, and that it may lead to conflicts even within single families.
