“But the people couldn’t believe, for as Isaiah also said, “The Lord has blinded their eyes and hardened their hearts— so that their eyes cannot see, and their hearts cannot understand, and they cannot turn to me and have me heal them.” Isaiah was referring to Jesus when he said this, because he saw the future and spoke of the Messiah’s glory.”
John 12:39-41 NLT
John, in these verses from chapter 12 of his Gospel, quoted a verse from Isaiah 6. Isaiah was a prophet in the time of King Uzziah, a good leader who died in 740 BC. He was one of the few Godly kings in those days and he brought stability in a politically unstable period of history. So when he died, Isaiah was concerned about what might happen next and he did something we all do, or should do, in times of worry and stress – he sought God’s counsel. And what better place to seek God than the temple. While there, he had an amazing vision of God – the detail is in Isaiah 6:1-4.
As well as a vision of God, though, Isaiah became aware of his sins, and the sins of the people. Isaiah 6:5, “Then I said, “It’s all over! I am doomed, for I am a sinful man. I have filthy lips, and I live among a people with filthy lips. Yet I have seen the King, the Lord of Heaven’s Armies”“. But equally, Isaiah realised that sinful though he was, it was only an act of God, through His servant the seraphim, that could forgive his sin. Isaiah was about to become a minister of God’s Word to his people and it was only with cleansed lips that this would be possible.
Then God ordained Isaiah as His messenger to the people – Isaiah 6:8, “Then I heard the Lord asking, “Whom should I send as a messenger to this people? Who will go for us?” I said, “Here I am. Send me”“. So he went out proclaiming God’s message of salvation to a people reluctant or unable to hear and understand the implications of what they were being told. In a way, Isaiah was a “type” of the coming Messiah, who was also proclaiming the message to a people seemingly deaf to the message of grace and truth, of eternal life to anyone who believed in the Son of God. Jesus taught the people by using a literary style we call parables and as we can see from Matthew 13, Jesus explained why He used such a medium to speak to the people. In response to a question from His disciples, Jesus said, “ … You are permitted to understand the secrets of the Kingdom of Heaven, but others are not. To those who listen to my teaching, more understanding will be given, and they will have an abundance of knowledge. But for those who are not listening, even what little understanding they have will be taken away from them. That is why I use these parables, For they look, but they don’t really see. They hear, but they don’t really listen or understand” (Matthew 13:11-13). Jesus went on to quote Isaiah’s prophecy, in Matthew 13:14-15.
Is there a reason why the Jewish people were afflicted with hard hearts and blind eyes? Of course, this condition is not unique amongst Jews by any means – any human being is sinful, and that in itself will harden hearts and make them resistant to God’s message. Heart, ear, and eye diseases are endemic, and always have been since the days of Adam. Jesus told a parable about seeds and soils, and He likened the state of the soil to the different conditions that can be found in the human heart. Those people with receptive hearts will have eyes and ears opened ready to hear and receive the seed of God. But most have stony soil on which seeds will wither and die. But even the disciples were accused by Jesus of having hard hearts following the feeding of the four thousand, as we read in Mark 8:17-18, “Jesus knew what they were saying, so he said, “Why are you arguing about having no bread? Don’t you know or understand even yet? Are your hearts too hard to take it in? ‘You have eyes—can’t you see? You have ears—can’t you hear?’ Don’t you remember anything at all?” No-one is exempt from having hard heart disease.
So how do we deal with the condition of having a hardened heart. There is only one remedy, and that is true repentance for our sins. We have to do this, because the effect of sin on our hearts is disastrous and leads to a hardening that will eventually shut God out of our lives. The Holy Spirit will call but we will be unable to hear Him. One of my favourite Psalms is 139, and we read the closing verses, “Search me, O God, and know my heart! Try me and know my thoughts! And see if there be any grievous way in me, and lead me in the way everlasting!” A dangerous prayer to pray but one that will lead to a softening of our hearts. And a soft heart allows God once again to bring His Word of truth into our spirits, leading us and guiding us in His ways.
Dear God. We pray today for Your Word to dwell deep within our hearts, keeping us soft and leant in Your hands. For Jesus’ sake. Amen.
