What does Luke 11:33 mean?
Over this chapter, Luke has accumulated a series of frustrating interactions between Jesus and the Jewish religious leaders. Critics have claimed Jesus' power to cast out demons comes from Satan, and Jesus has responded that such an arrangement would be incredibly foolish on Satan's part. The religious leaders have demanded more signs, and He has said they have seen enough but He'll give one more: the spread of God-worship among Gentiles (Luke 11:14–32). After this section, He will enumerate the ways in which the Pharisees and lawyers misapply the Mosaic law and carry on the tradition of killing the prophets (Luke 11:37–54).Here, Jesus uses the concept of light and darkness. "Light" is a common biblical theme representing truth, goodness, knowledge, and so forth. Jesus intends to show that His detractors have all the light—more than enough truth—needed to understand who He is. Yet their minds are so filled with darkness that they are blinded to what is obvious (Luke 11:33–36).
The "light" is the truth that Jesus is the Messiah. Jesus has proved this by performing specific miracles that match the Old Testament prophecies of the Messiah (Isaiah 35:5–6; Luke 7:21–22; 11:14). Instead of sharing this light with the Jewish people, the Pharisees and scribes hide it. They make false accusations and claim they need more proof (Luke 11:15–16). Jesus follows a progression: those who know the light will reveal it, not hide it; those who reject the light do so because their perception is darkened; their perception is darkened because they are filled with darkness. If they were filled with light, they would share it.
