To me, humans seldom know what they are doing. They failed to reckon the legitimate way of conveying truth while using it exclusively on almost everything and on a daily basis.
Isaiah 6:9
And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not.
One of the characteristics of this way of conveying truth is illustratable though.
If the US government has a crucial message for its citizens, what should it do? It should employ a mass media to broadcast it to all that states, not just California or Texa but all the states. That is, the agent doing the broadcasting must be US-facing.
Similarly, God's message is explicitly enforced by the command that the gospel must be preached to all nations, making it human-facing. Hinduism on the other hand, is like the US government has a crucial message for all its citizen but only annonounces it in Texas. Hindu gods only broadcast in India. They don't know that the legit way is in terms of conveying truths amongst humans.
It is because humans failed to reckon the legit way of conveying truth that Satan can make use of this very human weakness to create lies to fool all mankind.
The famous verse,
2 Corinthians 4:4
The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ, who is the image of God.

Poor Isaiah I am not sure he knew at the start what he signed up for "send me"
Isa 6:8 And I heard the voice of the Lord saying, “Whom shall I send, and who will go for us?” Then I said, “Here I am! Send me.” And he said, “Go, and say to this people: “‘Keep on hearing, but do not understand; keep on seeing, but do not perceive.’ Make the heart of this people dull, and their ears heavy, and blind their eyes; lest they see with their eyes, and hear with their ears, and understand with their hearts, and turn and be healed.” Then I said, “How long, O Lord?” And he said: “Until cities lie waste without inhabitant, and houses without people, and the land is a desolate waste, and the LORD removes people far away, and the forsaken places are many in the midst of the land.
See his Question " how long" I am going to tell them and now I know what the unchangeable purpose is ( to Make hearts dull and blind them) in doing so how long?
Then Jesus in explaining the text says:
Mat 13:10 Then the disciples came and said to him, “Why do you speak to them in parables?” And he answered them, “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. 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. Indeed, in their case the prophecy of Isaiah is fulfilled that says: “‘“You will indeed hear but never understand, and you will indeed see but never perceive.” 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.’ But blessed are your eyes, for they see, and your ears, for they hear. For truly, I say to you, many prophets and righteous people longed to see what you see, and did not see it, and to hear what you hear, and did not hear it.
Mat 13:10 Then the disciples came and said to him, “Why do you speak to them in parables?”
Mat 13:11 And he answered them, “To you it has been given to know the secrets of the kingdom of heaven, but to them it has not been given.
The knowledge secrets of the kingdom were given to whom, the apostles. Who gave them the knowledge? God the Father gave them the knowledge.
Flesh and blood has not reveled this but the Father which is in heaven.
Mat 13:12 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.
The one who has “what” will more be given to the measure of abundance?
The one who has not knowledge, what knowledge he has will be taken away. How will it be taken away?
Mat 13:13 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.
Jesus uses the parables “this= verse 12, taking away” to take away knowledge. Why does he do it this way because they do not see, nor hear, nor understand. (confusion)
Mat 13:14 Indeed, in their case the prophecy of Isaiah is fulfilled that says: “‘“You will indeed hear but never understand, and you will indeed see but never perceive.”
In their case “who’s case”? The ones who do not see, hear or understand. They will NEVER understand, nor perceive.
Mat 13:15 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.’
Lest they should see and hear and understand, Jesus would have to heal them in direct conflict with Isaiah, so he used parables so they could not and would not see, hear or understand.
Their are two clear groups those to whom things are given and others who have not been given.
How long... Until he accomplished all he pleases, in the way he has determined and purposed according to His good pleasure.
In Him,
