There’s no doubting Jack Chick’s sincerity but a lot of his depictions were something else. Case in point: the meter maid’s trike with a guillotine on the back.
Yeah, that one is rather striking.
I think it is well-within the realm of possibility that there will in fact be portable guillotines - because so many Tribulation Saints will (rightly) refuse the Mark of the Beast (thusly saving their eternal souls - Revelation 20:4)
The story, apparently, on Jack Chick is that he used to preach in prisons (etc.) with a flip-chart and he would illustrate his sermons that way.
Then one day, someone suggested to him that his illustrations be put in little books......
