What does the Bible say about division among Christians?

In the Gospel of John, Jesus is described as a source of division among people. John 7:43 states, 'So there was a division among the people because of Him.' This indicates that following Christ inevitably creates a separation from the world and its values. To achieve true unity with God, believers must experience division from worldly ideals and falsehoods. Scriptures like Matthew 10:34 confirm that Jesus did not come to bring peace but a sword, emphasizing the necessity of division when it comes to allegiance to Christ versus the world.
