Daniel Valles from Informed Christians runs a biblical channel on YouTube. He follows the news and keeps Christians up to date on current events in relation to bible prophecy. He usually doesn't mention the "flat earth" topic, but he doesn't believe in the spinning globe. I've seen Flat-Earthers share this PDF around, and thought it deserved an article on it in case some people weren't aware.
This is a well thought-out 40 page PDF that you can share with your family and friends, written with a critical eye and from a Christian perspective. Hope you enjoy it.
