What does the Bible say about the purpose of fire in Luke 12?

In Luke 12:49, Jesus speaks of sending fire upon the earth, which symbolizes purification and the destruction of false doctrines. This fire is not literal, but rather represents the gospel truth that not only consumes falsehood but also reveals the glory of God. The intention is to sanitize the teachings of the day, especially the man-made traditions that obscured God's truth. As fire destroys impurities, so does Christ's gospel eradicate the false beliefs and self-righteousness that hinder true faith.
