''Father Abraham, have mercy upon me and send Lazarus....'' Abraham could not grant the rich man's request above because

In the story told by Jesus in Luke 16:19-31, the rich man had died and was in torment in Hades, while Lazarus, who had been poor and covered with sores during his life, was in the comfort of Abraham's side in heaven. The rich man begged Abraham to send Lazarus to dip his finger in water and cool his tongue, but Abraham told him that there was a great chasm between them that could not be crossed, so it was impossible to grant the rich man's request. Therefore, the reason Abraham could not grant the rich man's request was that there was an unbridgeable gap between the place where they were, and not because of any wrongdoing on Abraham's part or because of any debt that Abraham owed the rich man.
