Some thoughts on Allegory

Written and interpreted as an allegory, the bible message is clear, simple, and understandable. But the concept of allegory is not accessible to the vast majority of humans. They simple do not have the IQ, the intellectual capacity to read something and NOT interpret it literally. So I ask why the message of the bible was intended to be hidden from so many, and available to so few?

Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.

Ezekiel 40:16

And there were narrow windows to the little chambers, and to their posts within the gate round about, and likewise to the arches: and windows were round about inward: and upon each post were palm trees.

 

Numbers 22:26

And the angel of the Lord went further, and stood in a narrow place, where was no way to turn either to the right hand or to the left.
