I came across a wonderful website full of all kinds of information on the Rapture and the Second Coming. It's called Amy's Speculation Corner, and I've asked Amy's permission to post her link. I found her study of the Psalm 83 war as well as the Gog/Magog war spoken of in Ezekiel to be extremely in-depth and eye-opening.
Amy gives cross references to the prophecy Scriptures and a few maps of what the landscape looks like according to prophecy. Grab a cup of coffee and read the entire study. Very informative!
