Question is what is the deception?

Personally, I believe it is the notion that we can achieve heaven on earth, or that if only we had a "Christian" government (i.e. a theocracy, as opposed to a secular government inhabited by Christians, which is something different) it would solve all our problems.

Correct. Our lives need to be a theocracy. Our nation does not.

[Just mythoughts]

Well I do agree in part, however, more to the picture note these words

I also will choose their delusions, and will bring their fears upon them;

because when I called, none did answer;

when I spake, they did not hear: but they did evil before MINE eyes, and chose that in which I delighted not.

[from the old a second witness is given in the new]

and for this cause God shall send them strong delusion, that they should believe a lie;

That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
