Daily Bitachon: Sha'ar Habechina Welcome back to our series on Sha'ar Habechina . We are continuing our journey through the human being as a "miniature world," viewed through the lens of the Chazon Ish . He points out something fascinating: most people are completely unaware of the vast armies standing guard over them, toiling tirelessly to preserve their lives. Just as a country has a military to defend its borders, there is a literal army inside of you. The Internal "Iron Dome" Who are these soldiers? They are your white blood cells . Your body contains billions of living cells that belong to you, along with billions of "inhabitants"—microbes and bacteria in your gut—that live alongside you. Every day, we face biological "terrorists": viruses, fungi, and harmful bacteria. It isn't just geopolitical threats like ballistic missiles; these wars are happening under your skin right now. God installed an Internal Iron Dome that intercepts these threats. If we could hear what was happening inside our veins, we would hear sirens going off constantly. I remember an elementary school teacher describing a simple infection or a "pus pimple" in a graphic way: she said that when you see pus, you are looking at the battlefield. Those are the "dead soldiers"—the white blood cells that gave their lives to protect you. A high white blood cell count on a medical report is simply a dispatch from the front lines, telling you that a war is being waged on your behalf. Note: This isn't just a science class. This is the Torah of the Chazon Ish, the Gadol Hador . These insights are so holy that one must say Birkat HaTorah (the blessings over Torah study) before learning them. Communication: The Mouth and the Ear Now, imagine this "robot" is perfect—it sees, moves, and has a defense system. But what is it worth if it cannot communicate? At first, you might imagine the Inventor fashioned a machine that chirps a variety of sounds. We call this machine a mouth . It is an incredibly expensive, highly complex piece of engineering. But a "chirping machine" is useless without a sensor. So, corresponding to the mouth, the Inventor created a machine that senses every sound wave: the ear . This presents a massive challenge to the theory of random evolution. What use is a voice box if no one is listening? What is the purpose of an ear if nothing is making sound? They are two separate, highly complex systems that must exist simultaneously to have any value. Yet here we are, the "lucky survivors" of this perfect design. Intellect and Continuity Beyond the physical, God granted us intellect . Without it, we would be no different from an ox eating grass. He gave us wisdom so we could fulfill our unique role in creation. Then, the Inventor addressed the problem of "stock." He didn't want to manually build every single robot; He wanted them to procreate. He created male and female so that these two machines could continue the "production line" forever. Imagine buying a robot on Amazon and the seller saying, "Just buy these two, and you'll never need to buy another one again." We are so accustomed to this marvel that we don't notice it, but for thousands of years, billions of people have been produced "undercover" in the mother's womb, all running on Divine autopilot. The Self-Healing Body The Inventor also built in a repair shop. When you cut yourself and blood flows, your organs and tissues immediately send "coagulants" to freeze the surface and stop the leak. Eventually, the body fuses the flesh back together, creating new membranes and scar tissue. And for those serious battles where our internal army needs help? God created a "storehouse of mercenaries"— herbs, vegetation, and medicines —hidden in the natural world to serve as antibiotics. Conclusion: The Ultimate App The Chazon Ish notes that the only thing stopping us from seeing this is the "constant busyness" of life. We get so excited about an iPhone and its gazillions of apps. You can open your front door or talk to someone across the world and you say, "Wow!" But hold on—God is the original Developer. Your eye is an app. Your ear is an app. Your tongue is an app. Need to charge your battery? Take a nap. We get so impressed by what human beings can build. It's time we get excited about what God has already done.
