"And God said, there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so." Genesis 1:6-7
Miracle of God's Nature
Water has been daptly called the most uncommon of the common substances. What a marvelously versatile substance water is! Its molecules lock together in flinty embrace as ice, and think of all the uses of ice in our economy.
In another form, water covers the earth with a dry, protective blanket of snow in the winter, and piles up ton after ton of stored water in the valleys of the mountains. It falls as rain to quench the thirst of the dry earth in the spring and summer; it feeds our rivers and fills our oceans and lakes. It shades us from the heat of the sun as vapor in the clouds. As steam it drives powerful machinery.
Truly, water is one of the greatest gifts of God to man.
We all know that a world without water would be lifeless, but a world in which water followed the customary laws of physics would also soon become lifeless! Water, unlike any other substance (except bismuth), is heaviest at 4 degrees centigrade, slightly above freezing. Above that and below that it is lighter. Because of this, ice floats and water freezes from the top down.
If ice were heavier than water, instead of lighter, when a lake froze, the ice would sink and the water would soon be solid ice from the bottom up. All rivers would freeze solid! This would kill all fish, prevent thawing in the spring and so upset the scheme of things as to make life on earth impossible. Who changed the law that cold contracts and heat expands, when it applies to water? The Creator designed it so.
Water has many other virtues that make it indispensable for a habitable earth. Water is nature's best air conditioner. Water has an immense capacity for storing heat energy. Thus, the oceans can absorb enough heat during summer to cool the air, and during the winter this heat is given off, thus moderating the cold weather. Though sea water weighs 800 times more than air, when it is vaporized by the heat of the sun, it is lighter than air and is lifted into the cloud! This remarkable miracle makes rain possible.
Ages before the modern science of meteorology, the Bible revealed the "rain cycle."
"The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to his circuits. All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again" Ecclesiastes 1:6-7.
Modern science describes this amazing rain cycle:
"The energy of the sun received on a square mile of ocean will evaporate and raise about 5,435 tons of water vapor into the air in an hour. Water vapor rises to considerable heights and moves with the air currents (over the continents). When the air holding water vapor cools, the vapor condenses into billions of tiny droplets, so small it takes about 8,000,000 to make a fair-sized drop of rain! ...Each of these tiny droplets must have a tiny particle of dust on which it clings. As this condensation takes place in the atmosphere, clouds are formed; when the air has been chilled sufficiently to form clouds these tiny droplets coalesce and form larger drops, and when the air can no longer support them, it rains." (Condensed from Science Digest)
Then too, water is "the closest approach to a true universal solvent" that we know. It dissolves with ease a fantastic variety of materials, and yet it does NOT dissolve the rocks of the seashore, otherwise the continents would melt away and disappear in the oceans. Did all these strange and wonderful characteristics of water just happen? Hardly. Water with all its marvelous characteristics is one of God's creations.
"And God said, there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so" Genesis 1:6-7.
What causes a rainbow?
The technical details of rainbow formation were first analyzed by Isaac Newton in 1665. His brilliant optics work concerning reflection and refraction certainly does not detract from the beauty and promise of the rainbow. On the contrary, Newton's scientific insights show the marvelous complexity of creation. The rainbow is a gracious pledge that God will not destroy the earth a second time with a worldwide flood.
"I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth. And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud: And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh" (Genesis 9:13-15).
A rainbow occurs when raindrops and sunshine cross paths. Sunlight consists of all the colors of light, which add together to make white illumination. When sunlight enters water drops, it reflects off their inside surfaces. While passing through the droplets, the light also separates into its component colors, which is similar to the effect of a glass prism. Each falling water drop actually flashes its colors to the observer for just an instant, before another drop takes its place.
A rainbow is usually seen in the opposite direction in the sky from the sun. The rainbow light is reflected to the eye at an angle of 42 degrees to the original ray of sunlight. The bow shape is actually part of a cone of light that is cut off by the horizon. If you travel toward the end of a rainbow, it will move ahead of you, maintaining its shape. Thus, there is no real end to a rainbow, and no pot of gold waiting there. Because the 42 degree angle is measured from each individual observer's eye, no two people see exactly the same rainbow. Every person is at the center of his or her own particular cone of colored light. From the high vantage point of a mountaintop or an airplane a complete circle of rainbow light sometimes can be seen.
The bright, primary rainbow has red on the outer edge and blue within. Higher in the sky there is always another, dimmer rainbow with the order of colors reversed. This secondary rainbow results from additional reflection of sunlight through the raindrops. It is most visible when there are dark clouds behind it. Look for the second bow high in the sky the next time rainbow colors appear. Some observers have even reported seeing third and fourth rainbows above the first two.
