It seems some, or many, in which I have witnessed are under this veil. They do not see clearly. It is as if they are seeing things through a filter. A filter contrary to truth & reality. You can tell these people the truth, you can show them the truth, you can even provide photos, videos, eye witness testimonials, yet they still do not either want to accept it, nor believe it. It is as if they have consumed lies for so long, it is the only reality or truth that they know, or want to believe. It is as if they are in this metaphoric slumber, unable to wake from a dream in which they have been led to believe.
In the bible it talks of such “clouded glass” and “veils” as well.
“We don’t yet see things clearly. We’re squinting in a fog, peering through a mist. But it won’t be long before the weather clears and the sun shines bright! We’ll see it all then, see it all as clearly as God sees us, knowing him directly just as he knows us!” – 1 Corinthians 13:12 MSG
