The design of the human body demands the existence of a Designer.
Have you ever pondered all that’s involved in the function of the human brain? The brain is made up of around 100 billion nerve cells. Each cell is connected to another 10,000 cells. This means that, in total, we have around 1,000 trillion connections in our brains. These are ultimately responsible for who we are. Our brains control the decisions we make, the way we move, the way we feel. The functions of the brain keep the intricate organs of the body working in harmony and balance with each other. The human brain is truly remarkable!
The four parts of the brain have different functions. For example, the cerebrum is responsible for thoughts, such as reasoning, planning, emotions, problem-solving, and perceptions. The cerebellum works to maintain balance, muscle tone, and gait. The brain stem is especially important since it deals with blood pressure, respiration, and heart rate. Finally, the limbic system controls hunger, thirst, memory, fear, and emotions. These different processes must work together.
That’s the way it is with the whole human body. Lungs and heart, nerves and muscles, all perform incredibly complicated tasks that depend on other incredibly complicated tasks, directed by your brain. No wonder the psalmist concluded that the human body speaks loud and clear of a wonderful Creator:
“I will praise You, for I am fearfully and wonderfully made; marvelous are Your works, and that my soul knows very well” (Psalm 139:14).
We don’t have to go far to find the “works” of God. The evidence right in our own bodies points to an infinitely skillful Designer. Consider the chances of a stomach, brain, heart, lungs, arteries, veins, kidneys, ears, eyes, and teeth all developing together and beginning to function at the same moment in time. What is the most reasonable explanation for the design of the human body?
“Then God said, ‘Let Us make man in Our image, according to Our likeness’ . . . . so God created man in His own image; in the image of God He created him; male and female He created them” (Genesis 1:26, 27).
The first man and woman could not just have happened. The Bible affirms that God designed us in His image. He is the great Engineering Intelligence who designed us and brought us into being.
