Ghosts don’t change people, God does
But Abraham said, ‘If they won’t listen to Moses and the prophets, they won’t listen even if someone rises from the dead.’ ”
At first glance this verse seems to be completely false. Surely if someone returned from the dead and spoke to me I would listen to them infinitely more than I would listen to the words of Deuteronomy or Malachi!
However I do think the point is sound because it reveals the power of the human will. No external pressure or evidence will by itself change one’s perspective on God. Only the words of God breathed into the heart of man can affect lasting change. The rich man and his brothers were radically devoted worshipers of money and not even a ghost would be able to detach them from their devotion. It worked in Dickens “a Christmas Carol” but Jesus is saying it wouldn’t work in real life. I suspect Jesus is right. For someone’s allegiance to change to God from money, sex, power, fame, self love, materialism or any such idols as these It will only be the words of God that do it.
