For I have come down from heaven not to do my will but to do the will of him who sent me.

Jesus makes 4 bold points in this statement:

  1. He was originally in heaven and came from there to earth
  2. He did not come to do His own will
  3. His goal on earth is to do God’s will
  4. He was sent by God

Points 1 and 4 would be particularly irritating to the Jews.
