How does the gospel cause division?

In Acts 19, the arrival of the gospel in Ephesus creates a stir that leads to confusion and division among the people. This aligns with Luke 12:51, where Jesus states that He came to bring division, not peace. The gospel's truth stands in stark contrast to the lies of idolatry and self-righteousness, prompting a defensive response from those whose livelihoods and beliefs are threatened. This division is not merely conflict; it represents a crucial aspect of the gospel's power to illuminate the hearts of men, revealing their true nature and need for redemption. The division is ultimately a manifestation of the dividing line between light and darkness.
