How is Abraham able to speak to the rich man in hell if there is a chasm between them? And Abraham is speaking with Lazarus who is in hell? How is this possible since we have a great chasm between us? Does God give efficacious grace for us to speak to people in hell? I don't think so because than we'd be sad? So why does Abraham speak to someone in hell?
So it was that the beggar died, and was carried by the angels to Abraham's bosom. The rich man also died and was buried. And being in torments in Hades, he lifted up his eyes and saw Abraham afar off, and Lazarus in his bosom.
Then he cried and said,'Father Abraham, have mercy on me, and send Lazarus that he may dip the tip of his finger in water and cool my tongue; for I am tormented in this flame.'
But Abraham said, 'Son, remember that in your lifetime you received your good things, and likewise Lazarus evil things; but now he is comforted and you are tormented. And besides all this, between us and you there is a great gulf fixed, so that those who want to pass from here to you cannot, nor can those from there pass to us.'
Then he said, 'I beg you therefore, father, that you would send him to my father's house, 'for I have five brothers, that he may testify to them, lest they also come to this place of torment.'
Abraham said to him, 'They have Moses and the prophets; let them hear them.'
And he said, 'No, father Abraham; but if one goes to them from the dead, they will repent.'
But he said to him, 'If they do not hear Moses and the prophets, neither will they be persuaded though one rise from the dead.' (Luke 16:22-31, NKJV)
