It’s a miracle that we woke up today, that we opened our eyes, took a deep breath, planted our feet on the floor, and then shuffled off to the coffee maker, the start of another day. For all those seemingly simple physical acts to happen, our human bodies had to carry out a symphony of millions of interconnected and complicated impulses. Brain synapses fired off in a millisecond as blood coursed through veins. Oxygen pulled into the lungs; muscles contracted and stretched—all to just get us out of bed.
Then God formed man from the dust of the ground, and breathed into his nostrils the breath of life; and the man became a living being. — The Bible, (ESV) Genesis 2:7
The human body is a collection of miracles. On average, the human brain has about 100 billion nerve cells that fire impulses at speeds of nearly 280 km/h per hour. The average human heart beats 3 billion times in a lifetime, pumping 181 million liters of blood, which travels 96,000 km/h on its journey through the body every day. In the last 24 hours, you’ve breathed almost 24,000 times, in and out … in and out.
Our brain is nourished by our body’s network of blood vessels. With each heartbeat, arteries carry about 20 to 25 percent of our blood to our brain, where billions of cells use about 20 percent of the oxygen and fuel our blood carries.
Consider that our hands can lovingly cradle the most fragile of infants, but are also capable of pulling great weights, or do harm. The tongue, which for its size is the strongest muscle in the body, can spew forth hateful language or tell someone, “I love you.” With just a wink of an eye, we can reassure a nervous child, and in another blink with that same eye, we can fan the flames of hate and resentment. To experience this thing we call life, we need our bodies to function perfectly. Our bodies somehow sustain themselves, grow, repair, and stay alive till the very end.
There are trillions of deliberate, calculated chemical reactions and exchanges going on within us every second and everything runs like clockwork.
We must conclude that a very brilliant, sophisticated engineer played a characteristic role in making this work. Despite our infinitesimal knowledge of the body, if we could get acquainted with this engineer and builder of life formerly unanswered questions would be resolved and would start making sense.
