The devil uses his man, the Antichrist, to
set up this one, world religion. One of the
things about the Antichrist and his religion
is that he:

" And deceiveth them that dwell on the earth
by the means of those miracles which he had
power to do in the sight of the beast; saying to
them that dwell on the earth, that they should
make an image to the beast, which had the
wound by a sword, and did live.
And he had power to give life unto the image
of the beast, that the image of the beast should
both speak, and cause that as many as would
not worship the image of the beast should be
killed." Revelation 13:14-15
