What does John 12:9 mean?
The stated purpose of the gospel of John is providing proof that Jesus Christ is the divine Promised One (John 20:30–31). To this point, John has provided seven examples of miracles, numerous witnesses, extensive conversations, and other convincing points. People who lived during those times would have seen and heard even more. Among those amazing miracles was the raising of Lazarus, whom Jesus brought back to life after four days in a tomb (John 11:38–44). This occurred in the town of Bethany, extremely close to Jerusalem (John 11:18). Chapter 12 begins with a celebration in Bethany (John 12:1–2), which provides curious people the chance to go and see for themselves if Lazarus was truly alive.John often uses the phrase "the Jews" to refer either to the religious leaders of Jerusalem or their immediate followers. In this case, he means the latter: the people of the city. Word of Lazarus' spectacular resurrection has led many of those people to come and visit. Apparently, for some of them, seeing was believing—they recognized what they saw as proof of Jesus' divine power and authority (John 12:11).
In response to Jesus' raising of Lazarus, groups like the Pharisees and Sadducees banded together to have Jesus killed (John 11:53). Not only are they willing to assassinate a miracle-worker, they're open to murdering an innocent man who was the subject of a miracle, as well (John 12:10).
