I think the rich man and Lazarus parable is actually referring to the resurrection of Lazarus. I think this event specifically happened to prove to the Sanhedrin that Jesus was the messiah:
Luke 16:30 And he said, Nay, father Abraham: but if one went unto them from the dead, they will repent.
31 And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.
The resurrection of Lazarus was "in the face" of the Sanhedrin, but they still failed to comprehend who Jesus was.
