After Jesus' authority had been questioned, today we find the Jews questioning Jesus' identity. They thought because they knew about Him, where He lived and where He grew up, that He couldn't possibly be the Messiah. But they missed the key point that Jesus didn't come on His own authority, but by the authority of the One who sent Him, God. As He spoke, many believed, and this caused the Pharisees to have Him arrested. This is when Jesus reminded them that He was about to leave them, and one day they would look for Him (the Messiah), but they would not find Him any longer.
