For this people’s heart has grown dull, and with their ears they can barely hear, and their eyes they have closed, lest they should see with their eyes and hear with their ears and understand with their heart and turn, and I would heal them.’
Matthew 13:15 ESV
Jesus didn’t throw treasures to pigs, or give what is sacred to dogs. He often spoke to His unbelieving hearers in parables. If they’d had spiritual insight they would have understood His illustrations, but their heart had grown dull.
They barely heard what Jesus was saying. Yes, their ears took in the sounds and they even knew what He was saying, but they didn’t know the meaning of the parables. This was explained by Jesus to the disciples later.
The people couldn’t see that when Jesus described the kingdom of heaven, He was talking about spiritual truths. He wasnt talking about a physical kingdom that would overturn the Roman Empire in Judea and Galilee. They were blind to heavenly realities.
Having said all that, if the people did see, hear and understand, they would have been healed. Again, this is a spiritual meaning. It’s not that they were literally deaf and blind with a heart condition. But they needed spiritual insight, listening, and open hearts. If they had have turned, God would have healed them.
“Father in heaven, we’re grateful that You’re not willing that any should perish, but that all should come to repentance and faith in You. Please work out Your perfect will in our lives, and heal us of sin sickness we pray. In Your name, amen”
