Although the Bible is not a science book, there are statements throughout its ancient pages which correspond to scientific discoveries of the modern era. God inspired the biblical authors to record certain processes of nature that would only be understood thousands of years in their future.
These are a few:
Number of stars: The unaided eye can only observe a few thousand stars in the best of circumstances. Yet the Bible often asserts that the stars of heaven are as the grains of sand on the seashore (Genesis 22:17) which cannot be numbered (Jeremiah 33:22)
Earth’s orbit: The Bible describes the earth as suspended on nothing (Job 26:7). The gravitational pull of the Sun, moon and planets is invisible to the naked eye, hence the phrase “suspended on nothing.”
Sphere of the earth: The shape of the earth is spherical according to Isaiah 40:22. This was said in a time when many cultures believed in a flat earth.
Meteorological Cycle: The circulation of the atmosphere is mentioned in Ecclesiastes 1:6. It refers to the weight of the wind (Job 28:25) thousands of years before the air was understood to have mass, weight and density. Job also referred to the hydrological cycle of evaporation, condensation and precipitation (Job 36:27-29).
MIcrobiology: Germs were unknown until the 19th century. But the Old Testament laws about hygiene were very strict and were put to use during medieval times to combat the spread of the plague.
Bloodletting prohibited: The early medical procedure known as bloodletting was thought to cleanse the patient of impurities. Leviticus 17:11-14 refutes this false idea describing the life-giving power of the blood.
Circumcision on eighth day: The OT declared that a male child was to be circumcised on his eighth day. Science has discovered that this is the best time for this surgical procedure due to the increased clotting factor that naturally occurs in the baby’s body.
These are just a few examples prescribed or described in the Bible which science has only recently come to understand.
The best explanation for this early insight must be to recognize the inspired character of the Bible. God has revealed himself in this book (II Timothy 3:16; Romans 15:4) and His word is truth (John 17:17).
