Luke 17 : 34-36 :
"I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left.[SUP] [/SUP]Two women shall be grinding together; the one shall be taken, and the other left.Two men shall be in the field; the one shall be taken, and the other left."
Even our Lord and savior hints to us that it's going to be dark in one part of the world when He returns and light in another part of the world. You CANNOT have that with a flat Earth. On a flat Earth, there would be constantly light, all over the world. Any many times, the word WORLD is mentioned in the Scriptures....a world is NOT a flat object. Jupiter, a world, Saturn a world, Venus, a world. It's safe to assume our Lord knows the Earth is round and not a flat disk or plane.
