Take a survey and get the book
Heaven and Hell: Are They Real, by Christopher Hudson,
free.
The survey is at
https://harpercollins.co1.qualtrics....?Source=Bibles. After you complete the survey, you will click on a link which will take you to a webpage where you give your email address. You will receive a link at that email address, to the
free ebook.
The survey states that it will take 10-12 minutes to complete it. In previous surveys from the same source, Thomas Nelson/HarperCollins, I think that they understated it; for this survey, it seems that they have overstated it somewhat--I estimate that I spent only 5-10 minutes on it.
