Mighty Angel , Small Book

Then John sees another awesome angel coming down from Heaven. He has a rainbow for a halo and his face shines like the sun—you know, the usual.
The angel hands John a tiny scroll and tells him to eat it. Fair warning: The scroll will taste like honey going down, but is going to leave a bitter taste in John's stomach.
John, of course, gobbles up the scroll, because when a magnificent angel with a face like the sun tells you to eat a scroll, you eat it.
