One of the many interesting facts found in Isaiah is that it was written over 2700 years ago. Why is that so interesting? Because in 700 BC, the conventional wisdom was that the earth was flat. Not only did the common man think it was flat, but the intellectuals were also convinced of this. (The prevailing scientific theory was that the earth was supported on the back of a giant turtle, which is still embraced today in some cultures. (What the turtle was standing on has never been fully explored.)
Yet even though all mankind was convinced of the flatness of the earth, note this verse from Isaiah 40:22: “It is He who sits above the circle of the earth.”
The word circle would have never been used if a mortal had written that book unassisted. But God inspired the man that wrote it, ensuring that the Bible was correct in its terminology. The Bible will always withstand scientific challenges thrown at it. In fact, not only has science never proven any part of the Bible wrong, it actually continually proves it to be right.
