Honestly, I don't care what shape the Earth is in. Square, sphere, triangle..... Who cares??? (Although, I might think twice before going on a cruise, if it were indeed flat.) My personal belief is the Earth is round. Why? Because all of the other planets are round. The moon is round. We can SEE them. Why would our planet, which is subject to the same laws of physics as all the other planets and moons, be any different?
Bottom line..... Jesus created this planet and if He chose to make it different, I'm sure there was a very good reason. If He chose to make it round like all the other planets, I'm sure there was a very good reason.
