Science in the Bible – Water Cycle

(2 Minute Read)

Thousands of rivers hourly disgorge billions of gallons of water into the oceans.

For example, the Mississippi River alone pours over six million gallons of water into the Gulf of Mexico every second.

What is the source of all this water that keeps pouring into the oceans?
Where does all the water go?
Why doesn’t the sea level rise?

The answer to these questions was not understood until the 17th century when French scientists Pierre Perrault (c. 1608–1680) and Edme Mariotte (c. 1620–1684) developed the concept of the hydrologic cycle.

Hydrologic Water Cycle

1. Water from rivers flows into the oceans.
2. Water evaporates from the oceans into clouds.
3. Water returns to land in the form of rain from clouds.
4. Water drains from the land back into the rivers.

Amazingly, the Bible alluded to this water cycle thousands of years before Perrault and Mariotte figured it out. The Biblical authors credited it to the Creator.

The prophet Amos writing 2,800 years ago said,
He who calls for the waters of the sea
And pours them out on the face of the earth,
The Lord is His name.
(Amos 9:6 NASB)

The book of Job (circa 2000 BC) says,
For He draws up the drops of water,
They distill rain from the mist,
Which the clouds pour down,
They drip upon man abundantly.
(Job 36:27-28 NASB)
He wraps up the waters in His clouds,
And the cloud does not burst under them.
(Job 26:8 NASB)

Solomon (circa 950 BC) said,
All the rivers flow into the sea,
Yet the sea is not full.
To the place where the rivers flow,
There they flow again.
(Ecclesiastes 1:7 NASB)

Science Catches Up to the Bible

Ancient thinkers like Aristotle (384–322 BC) did not understand the origin of rain. And they could not figure out why the sea level never rose despite the influx of waters from great rivers. But thousands of years ago the Bible hinted at the hydrologic cycle of evaporation, atmospheric transportation, distillation, and precipitation which today’s meteorologists understand.

How were the Biblical authors able to write about this so long before other men understood it?

Although the Bible is not primarily a science textbook, it does hint at many scientific truths like these and like those mentioned in this Science in the Bible series, truths that long pre-date their discovery by today’s scientists. This is strong evidence of divine authorship of the Bible.

Questions to Ponder

1. Do complaints about rainy weather honor the Creator?
2. Why does it take scientists so long to discover things when the clues are in the Bible all along?

Thy word is a lamp to my feet and a light to my path. (Psalm 119:105)


  1. It is for this reason that the Bible says that nature reflects the glory of the creator and that therefore man is inexcusable for not believing in him and his power. Do not believe why your eyes were blindfolded by the prince of this world.
