Puritanboard Brimstone
Some ladies in my church decided to read and study the old Frank Peretti book, "This Present Darkness" as a way to study angels and demons. I'm happy they are interested in studying, but I'm not at all happy about the book as it is egregiously bad. I want to suggest some positive alternatives, though I understand that a nonfiction work won't be as captivating and enjoyable a read as a fiction book... I'm not aware of many good books on the topic of angels and demons from a solid biblical perspective, much less a Reformed one. I do know about Sproul's book "Unseen Realities," but are there any others you would recommend?
