The gospel of the Kingdom of God was the most important news ever to be heralded to humanity. But, instead of taking it as good news, the majority of those living at that time, actually, received it as bad news. That gospel is still bad news for most people, even today.
On being asked, about the reason why He spoke in parables, Jesus revealed something that can be adjudged as quite mysterious to ordinary people: “This is why I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand” (Matthew 13:13) (ESV).
Were the parables designed to be advantageous to ordinary people, or not? The context that Jesus applied reveals that the parables were, actually, meant to mystify the understanding for the ordinary people. Those people would be left with the impression that they understood when the opposite would be true.
Interestingly, to His disciples Jesus did not speak in parables: “….To you it has been given to know the secrets of the kingdom of heaven, but to them it has not been given. For to the one who has, more will be given, and he will have an abundance, but from the one who has not, even what he has will be taken away” (Matthew 13:11-12) (ESV). Did Jesus practice favoritism?
There are some people who, obviously, get something from my writings, so that their lives get changed, never to be the same again. But there are also those who Jesus said would be seeing but unable to see, and hearing but unable to hear. In that process, even the little that those people have would be taken away.
