You appear to be making some leaps of logic, that do not seem to be supported by the scriptures that you quote.
"The kingdom of heaven is like hidden treasure lying buried in a field. The man who found it, buried it again.."
I will give you treasures from dark vaults, hoarded in secret places, that you may know that I am the Lord, the God of Israel who summons you by name. Isaiah 45:3
You have heard what I said; consider it well, and you must admit the truth of it. Now I show you new things, hidden things which you did not know before. Isaiah 48:6
"Time was when many were aghast at you, my people, so now many nations recoil at sight of him, and kings curl their lips in disgust. For they see what they had never been told and things unheard before fill their thoughts." Isaiah 52:14,15
