Water is necessary for life. Whenever astronomers look for life on other planets, they first look for water- no water then no life but if some water then there is possible life.
From the website - https://www.explainthatstuff.com/water.html, we get the following description.
"What is water?"
"We can answer that question in many different ways. Water is what wets windows when it rains, what we drink when we feel thirsty, and what covers about 70% of Earth's surface. But what exactly is it?"
"Chemically speaking, water is a liquid substance made of molecules—a single, large drop of water weighing 0.1g contains about 3 billion trillion (3,000,000,000,000,000,000,000) of them! Each molecule of water is made up of three atoms: two hydrogen atoms locked in a sort of triangle with one oxygen atom—giving us the famous chemical formula H2O. The slightly imbalanced structure of water molecules (explained in the box below) means they attract and stick to many different substances. That is also why all kinds of things will dissolve in water, which is sometimes called a universal solvent. Water can even dissolve the solid rocks from which our planet is made, though the process does take many years, decades, or even centuries."
"Water has no end of amazing properties. It comes in three wildly different kinds, it is heavy, it expands in a funny way, it can climb up walls."
"One of the unique things about water in the world around us is that it exists in three very different forms (or states of matter as they are known): solid, liquid, and gas. Ordinary, liquid water is the most familiar to us because water is a liquid under everyday conditions, but were also very familiar with solid water (ice) and gaseous water (steam and water vapor) as well"
Concerning water and life, I quote the website –
"Is water essential for life?"
"Water is certainly essential to the forms of life we have on Earth, which all have a common ancestry and require water to function. Life has been found in all kinds of extreme environments, operating at the limits of heat and cold and even without air. But every type of life we have discovered contains biological cells that require water to provide their operating environment. Cells simply could not function without it. It’s not just a matter of keeping them inflated and moving chemicals around – living cells are full of tiny complex mechanisms. Many of these mechanisms rely on different sections of molecules either working well with water, or not mixing with it. Proteins, for example, are the key worker molecules in living organisms. Proteins have to fold into particular shapes to carry out their roles, and it is the interaction with water by various parts of a protein molecule that tell it how to fold. Water isn’t just a solvent: it is intimately involved in the functioning of our magnificent cellular machinery."
These lay descriptions of water demonstrate its complexity, which is frankly past human full comprehension. In short, water is magic. Now we want from God overt demonstrations of power such as raising Lazarus from the dead, parting the Red Sea, or curing disease with a touch. Non-believers want these constant “proofs” of God to believe. As I discuss often in this blog, when something is plentiful it cannot be special, it cannot be a miracle. And nothing is ubiquitous as water. Yet it is life, and it comes from God. It’s properties so special that only it can sustain life. That is our physical life, God is immaterial and thus not made from water, but He made water so that we in our material bodies could live and thrive.
Water is discussed all through the Bible, its holiness revealed. At the Last Supper, Jesus shares wine, which is made of water, and bread which is about 30- 50% water. Water is used in baptism. Some form of water and food (which all has water content) is used for all religious ceremonies of all religions in the world.
Water is necessary for life materially as much as the Holy Spirit is necessary for life spiritually. Therefore, water is used as an analogy in many verses in the Bible
Here are just a few Bible quotes about water-
For I will pour water on the thirsty land, and streams on the dry ground; I will pour out my Spirit on your offspring, and my blessing on your descendants (Isaiah 44:3) The LORD will guide you always; he will satisfy your needs in a sun-scorched land and will strengthen your frame. You will be like a well-watered garden, like a spring whose waters never fail (Isaiah 58:11)
Jesus answered, “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit (John 3:5)
Jesus answered her, “If you knew the gift of God and who it is that asks you for a drink, you would have asked him and he would have given you living water.” (John 4:10)
But let justice roll on like a river, righteousness like a never-failing stream! (Amos 5:24)
I baptize you with water for repentance. But after me comes one who is more powerful than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire (Matthew 3:11)
You, God, are my God, earnestly I seek you; I thirst for you, my whole being longs for you, in a dry and parched land where there is no water (Psalms 63:1)
He said to me: “It is done. I am the Alpha and the Omega, the Beginning and the End. To the thirsty I will give water without cost from the spring of the water of life” (Revelation 21:6)
10 Jesus answered her, “If you knew the gift of God and who it is that asks you for a drink, you would have asked Him and he would have given you living water.”11 “Sir,” the woman said, “you have nothing to draw with and the well is deep. Where can you get this living water? 12 Are you greater than our father Jacob, who gave us the well and drank from it himself, as did also his sons and his livestock?”13 Jesus answered, “Everyone who drinks this water will be thirsty again,14 but whoever drinks the water I give them will never thirst. Indeed, the water I give them will become in them a spring of water welling up to eternal life.”15 The woman said to him, “Sir, give me this water so that I won’t get thirsty and have to keep coming here to draw water.” (John 4: 10-15)
In addition to the science of water, its magical properties. In addition to the mystical nature of water, it is symbolic of God taking care of our needs, our thirst. In addition to all this as are all things from God, there is pure beauty. Things of great worth from God are also beautiful. As I have stated many times, God is both the ultimate scientist and the ultimate artist. Water shows both sides of Him.
