In the Bible it is written, “It is he that sitteth upon the circle of the earth, and the inhabitants thereof are as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in.” (Is 40:22) Some site this verse as evidence that Earth is flat and not a ball (sphere), since a different Hebrew word would be used here if the author wanted to describe a ball rather than a circle.
However, if we read the text carefully, it does not say that Earth is a circle, but it implies that Earth has a circle. The Hebrew word circle is also translated circuit (Job 22:14) and compass. (Pr 8:27) The Scripture appears to teach that both Earth and its Heaven (atmosphere) have a circuit, or a circular route they travel together … an orbit if you will … an idea consistent with our modern heliocentric model, which long preceded its discovery.
This should come as no surprise since there can be no real conflict between Science and Scripture if God is the Author of both. (1Ti 6:20) Only a Spherical Earth model accounts for the sun actually rising and setting from an earthly perspective while also providing for time zones, for each hour of our 24 hour day always occurring somewhere on Earth, disproving all Flat Earth models by contradiction.
Here is a video (9 min) demonstrating this fact in an experiment you can do at home that 3rd graders should easily understand. In a more in-depth article, direct proof of the size and shape of Earth is found in considering the consistent behavior of the stars, which demonstrates that Earth is a sphere about 25 thousand miles in circumference.
