Jesus often spoke in parables and used stories to tell a simple message, yet hidden inside of the simple story or parable was a deeper meaning that was meant only for those who were truly seeking the will and word of God
One of these all by itself is the simple phrase that Jesus spoke, “he who has ears to hear, let him hear.
Like many things that Jesus and YHWH In the old testament said. They have multiple meanings that can be applied to different levels or depths of understanding.
The simplest one here is obviously, whoever has ears, a heart and thirst for knowing God (let) him (hear). The important keywords here are let and hear.
It will take a little background to fully develop the meaning behind them though. I will try to keep it short. In the beggining God created everything to be simple and perfect, he knew full well that man would fall into the deception of satan, and just like all other evil forces that think they can win against God he created a plan to not only save man from the deception but to eventually get evil to turn on itself and destroy itself in the end Because well that’s what evil does.
The first true fall of mankind happened with Eve at the tree because the fruit of that tree was sin itself, in other words eating from that tree allowed for man to produce the fruits of sin instead of the fruits of God.
The second fall happened at the tower of babel and the idiot nimrod, the king who made himself to be a god over men and built a city and tower that symbolized man’s worthless knowledge of technology and civilization that is always geared towards the enslavement of others in order to be in control and to fuel the ego of man into thinking himself to be a god. All of this is done under the deception of a better life for all in a city and kingdom that provides food, shelter and protection. But the end result is always the same, the ruling class creating false idols and false gods and then believing themself to be gods until inevitably their destruction comes on themself. It has happened over and over again with all empires throughout history and is currently happening in this one.
So the first falling away from God at the tree caused one degree of separation from God, but the falling away at the tower of babel caused another in the sense that now man had decided he would aspire to actually develop cities as a display and outlet for his ego, which caused God to divide the people into different nations and to confuse their ability to coordinate by creating different languages. This also came with a confusion about who God is and how to speak to and hear him. Slowly, God began to reveal himself back to man through Abraham and the promised seed of the woman. The main point here being that most people had become shut off to God and hearing him because they had become so confused with all of the other false gods and doing what was right in their own eyes.
So when Jesus said he who has ears let him hear. He was giving a command for something that had not been previously possible to now be possible. Let the confusion and veil that was placed on man at the tower of babel be lifted for those who are here to hear. Where else have we heard this word [let] get used as a commmand? Genesis 1:3 let there be light, let the waters separate, let the dry land appear.
It is important to understand that even though Jesus was the epitome of humbleness, he was the Son of God and carried all of his power and authority within himself but chose to refrain from using it so that his mission of living as a weak and fully mortal man could be accomplished. However, his words would not be bridled or restrained because he was the word and was sent by God to reveal to men the father through the very same word that is Jesus. Don’t let this confuse you, when God created everything he did so with his words, he commanded them into existence, and it’s of no coincidence that the more science explores the basic principles of the universe and how it works and is held together it always comes back to minute particles and strings vibrating at very specific frequencies. Which is what a spoken word is, vibrations traveling through space and matter to reach its destination. So when Jesus said let them hear, it was a command for their hearing and understanding of Gods words to be recognized and received and it was a command with no different and with no less power then the same words that created everything we see. but it was a command given only to those whom God had chosen to receive him.
It’s hard to understand why only some where allowed to hear and others were not but just as Jesus only spoke in parables to the crowd and when they continued to follow him asking for a sign and miracle he explained that they would have to eat his flesh and drink his blood, which only repulsed them and sent them away. He said this only because their hearts were not seeking God and his will but only their own self-satisfaction, which is evil. Because they were not seeking God, they did not deserve to see or hear his son, or understand that he came to open our ears and hearts to truly understand God and his heart, through his son Jesus.
