If Jesus symbolized the Pharisees through the rich man in the illustration of “The Rich man and Lazarus,” what did he gain by that except that it made them more revengeful that ultimately resulted in the murder of the messenger himself? If an act is going to increase the problem, why should one initiate it in the first place? In this way also, illustration served no purpose!
In the big picture, this is what happens. The selfish people take advantage of a supernatural person who has supposedly spoken some good proverbs and performed some super-human feats—presenting things (parables and proverbs) through such authority to get easy acceptance from readers. One can see such motives behind some of the parables/illustrations Jesus supposedly used. For example, some people wanted to convey the following:
Fraud in business is ok (16:1-12); but such fraudulent ones will end up in hell (Luke 16:19-31); yet there is a way to work around this situation—the rich have to give a portion of their ill-gotten wealth to the poor, and can go to heaven. (Mathew 25:31-46). See how the rich have responded to such a message—many orphanages and similar institutions came into existence with the rich sponsoring them and the management living in luxury while working in the name of the poor.
