Its difficult to tell what He meant - we werent there, otherwise we could have asked Him.
Personally I think this whole parable wasnt really about the rich man, nor was it about Lazarus. IMHO it was all about the unbelievers.
Well - let us think about that parable again - here we have a rich man - what was his name again? - yes, the rich man, doesnt have a name. AND we have a beggar or something, a poor man, his name is Lazarus - how many people actually had been given a name in those parables? - I cant think of any at the moment (just correct me if there is one more!). So we have Lazarus, not the poor beggar, or hobo, or duder, we have Lazarus and we know that he was poor, less fortunate and stuff.
The funny thing is that Lazarus became sort of rich in heaven, and the rich man sort of poor in hell... and the rich man wanted to have Lazarus sent to warn others
But Jesus said, they wouldnt believe, EVEN if somebody rose from the dead...
The important thing to me,here, is that Jesus CLAIMED, they wouldnt believe, even if somebody rose from the dead. Of course, Jesus knew that, but those people there might have thought, well, if somebody rose from the dead, everyone would believe.
One way or another, Jesus made true on His word! Lazarus finally rose from the dead, or from his sleep, which might be a symbol for the state of being dead, or maybe how God views the state of being dead.
So, IMHO this parable, primarily served as a warning, in general, to do good, to help those Lazarus people out, not to care too much about money as it wont do you any get, or can even get you in trouble some day. And Lazarus finally rising from the dead (I think the news of his comeback spread fast) was sort of the fulfillment of this parable. Heaven and hell? Who cares? - Its Lazarus finally rising from the dead IMHO
