The Blind Man and the End of John Chapter 9

In the Gospel of John, Jesus uses imagery to explain what he thinks is happening right before his eyes. We've got the gatekeeper, the gate, the sheep, the shepherd, the thieves and the robbers. Maybe we can have a bit of a discussion as to who, which image represents which person of that time because we even read in this Gospel today that it says that at first the here is quite didn't quite understand what Jesus was saying.
