Blood for Every Need
I understand that the blood flowing in our bodies is necessary for our functioning. In that case, it might be enough to distribute the blood evenly throughout our organs from the start. So why must the heart work continuously, like a pump, to deliver blood to every cell in the body?
Firstly, certain organs need more blood for their "regular functions." Thus, the heart's role is to "dispatch" blood to our body's organs according to each one's "demand." I ask: How does the heart "know" the dose of blood supply for each organ? Who "tells" it?
Secondly, the heart sends blood to the lungs, which are closest to it, while simultaneously sending blood to distant parts of the body. Each organ receives blood with the force suitable for it. And I ask: How does it manage to "time" the exact and exemplary strength of blood flow to the body's organs? If blood were sent to the lungs too forcefully, they would be damaged; if sent to the limbs too weakly, they wouldn't receive it, and they would necroge...
Thirdly, when the body is under effort, it delivers more blood "as reinforcement" to the needed organ. For example, when in danger or fear, the heart sends more blood to the brain so that the person can make good decisions and know how to act; during physical activity such as running, the heart pumps more blood to the legs to supply more oxygen to the muscles. I ask: How does the heart "know" which organ needs help and increased supply? How does the heart know to return to routine automatically?
Who gave the heart these instructions on how to operate? I don't control it! There is no doubt, man was created with such incredible wisdom and wonderful understanding, with wonderfully coordinated and integrated systems, each organ in its suitable place. Every material in exact doses, every action at the right time...

Fish in the Sea
Anyone who keeps an aquarium at home knows that a quality aquarium is much more than just a glass tank filled with water. To provide the best living conditions for the fish, the aquarium requires the highest quality equipment, such as a water pump, heating and cooling systems, a filter, air pumps, and more.
In an aquarium, which is almost entirely closed and sealed, oxygen cannot generate by itself, so it must be introduced artificially—through an air pump that produces oxygen bubbles that pass through a tube into the aquarium. This continuously provides the necessary amount of oxygen while stirring the water to distribute the oxygen throughout.
I wondered: In the depths of the sea, where there are no air pumps, how do fish receive the oxygen they need?
However, fish breathe the oxygen molecules (O2) dissolved in the water (and not the oxygen atoms found in the water compound molecules H2O). These oxygen molecules arrive at the water from the atmosphere and the release from aquatic plants during photosynthesis. Essentially, an enormous plant system within the ocean produces oxygen for the fish, with the sea water distributing the oxygen across the ocean.
It can be noticed that in natural water sources there is abundant, high-quality oxygen available at a consistent level, allowing fish to breathe and live without artificial methods. Could it be that this wondrous process, indicating a guiding and caring hand, emerged on its own without a creator and planner?

Who Set the Laws?
In our world, there are numerous natural laws, such as the law of gravity or the law of conservation of matter. Someone must have set these laws, because if there's a law, there must be a lawmaker! Who decided that the boiling point of water would be 100ºC, and the freezing point would be 0ºC? Who decided that gestation would last nine months? Who determined the composition of the air we breathe (approximately 78% nitrogen gas, about 21% oxygen gas, roughly 0.03% carbon dioxide, and the rest are other gases, making up less than one percent)? A precisely and consistently exact composition is critical for us to breathe!
We can go on and on... It's unnecessary to say that scientists have no answer to who set these laws!
Did these laws evolve by themselves, or did someone set them?
Every natural scientist seeks the answer to the questions "how, how much, and where," but cannot answer the reason question: Why and for what purpose does nature behave the way it does? The researcher can explain what the force of gravity is, how it is created, but cannot explain why it was created?!
Anyone who studies the human body and its various mechanisms is amazed at the level of sophistication and efficiency with which the human body operates. There are mechanisms so complex within the human body that it's impossible to say they were created without design. Just see how much wisdom there is in the human body: two eyes in our head like two cameras, seeing in three dimensions, ears – to hear, vocal cords – to speak, a brain – to understand and think, and hands – to write and grasp.
Friends, the word "nature" is just a very superficial expression of the tremendous wisdom found in creation, because it is in no way possible that a "natural" process without life force and intention created such an amazing world.
Patrolling the Body
Your environment is full of bacteria, an endless number of various particles floating in the air you breathe – dust, gas emissions, and more. Each of these that enters the body through breathing, eating, or through a wound can harm the body severely, even fatal. Every day you inhale about twenty billion particles.
Danger lurks within the body too – dead cells, damaged ones, malignant ones, or those invaded by a virus – these too are dangerous foes to the body.
Our health and even our very existence seem impossible in this dangerous world.
However, there is a complex and wonderful defense system, working day and night in your body, whose sophistication is beyond imagination. The natural immune system is what protects your existence and maintains your good health.
Tens of billions of "patrolling officers" – white blood cells called macrophages – patrol 24/7 along kilometers of the blood vessel network to identify and deal with every invading enemy.
When the macrophage identifies an enemy, a chain of actions begins to eliminate it: the macrophage pounces on the enemy, engulfs it, and digests it using chemicals that are secreted onto it from within the macrophage. At the same time, the macrophage presents identification marks of the enemy that it is destroying on its outer shell. The assumption is that the defeated virus is not the only invader in the body. Lymphocytes, a type of white blood cell, "read" the information from the macrophage and pass it on. This information summons reinforcements of fighting lymphocytes to help eliminate the invading viruses.
The information is also transferred to lymphocytes located in the lymph nodes, and they produce special antibodies specifically tailored for eradicating this type of virus, newly discovered in the body, and these antibodies attach themselves to each virus, their unique structure designed just for it.
How does the macrophage know to identify an enemy? And who provided it with the list of body enemies and their identification marks?
How does the lymphocyte, receiving the enemy's identification, know to create an antibody specifically designed uniquely to eliminate that particular virus?
Who established and determined the reliable communication system among the components of the immune system, working together so perfectly?

What Are We Eating?
The subject of kashrut and the prohibition of eating forbidden foods is fundamental in the Torah. Beyond all the halachic and spiritual aspects of the matter, let's consider: What do all the forbidden foods, which the creator of the world prohibited us from eating, have in common? We shall see the wisdom and depth in every commandment that the creator instructs us.
The creator of the world forbade us from eating predatory animals (for example, tigers), but allowed us to eat "herbivorous" animals (such as cows): Animals capable of "murdering," whose entire essence is a desire to hunt, prey, tear, and eat the flesh of other animals – these are forbidden to us!
The creator of the world forbade us from eating disgusting creatures, such as insects and cockroaches: These are creatures found in areas of filth, dirt, and disgust. There is a natural human aversion and repulsion towards them... These are animals the creator of the world does not want us to bring into our bodies and contaminate them.
The creator allowed us to eat animals with split hooves, all of which chew cud. Why is this important? These are animals whose meat is of the highest quality and cleanliness when it reaches our mouth. In contrast, the pig – its digestion is among the fastest: within 4 hours, what it eats becomes a part of its body. If it eats filth and dirt, within 4 hours, it reaches a person's plate. It's low-quality and unclean meat.
The creator of the world allowed us to eat non-predatory and non-disgusting animals, herbivorous animals with very high quality and clean meat. By doing so, the creator of the world is protecting our bodies and preventing the corruption of our souls...
