The Devils Eldest Son seems to be towards the End of his last Half-time; and if it be so, the Devils Whole-time, cannot but be very near its End.
I had to read this sentence a few times to figure out what he was saying. Once I did, though, it kind of put this introduction to the trails His goal here is to remind us that the Devil is here at work in the world and that his evil plans are leading toward his end game goals. This means that now is the time to persecute witches and devil worshippers. Anything that these children of God can do to stop or hinder the devil in his plans to defy the Lord are good actions. That way when you get into the bizarre accounts that follow the introduction you are primed to think that devil is working through these people, as opposed to thinking that these people were making their stories up on the spot.
