“From the time the world was created, people have seen the earth and sky and all that God made. They can clearly see his invisible qualities—his eternal power and divine nature. So they have no excuse whatsoever for not knowing God.” (Romans 1:20) NLT
Have you thought about how amazing our bodies are? Think back to middle school life science for a minute. Do you remember the complexity of a single cell? Every part of the cell has a purpose--a job it's meant to do. Ribosomes, Lysosomes, Mitochondria… Here’s a quick refresher if you’re interested:
Every cell has these parts, but each cell is designed for a different purpose (sensing a pattern?). Some cells are epithelial cells for your skin, others are used for muscles, etc. Four distinct types of tissue, which are organized into organs. Every organ has a purpose as well. Web MD says even the appendix apparently has a purpose! Who knew?
And then to top it all off, these organs are organized into systems where they all work together for a common purpose within the body. Your respiratory system comes complete with vocal chords that are in just the right place so that we can sing as obnoxiously as we want. Our digestive system basically amounts to a conveyor belt where each organ is appropriately placed so that the job it’s intended to do happens in the right sequence. Every system is critical to life! Remove one and you’re pretty much done for.
What about the rest of nature? Our moon revolves endlessly around this planet, because the Earth is constantly rotating which produces gravity. The earth's gravity can keep a moon in check while still being exactly the right amount for us to live. Its a perfect balance that prevents us from floating away but still allows us to jump and run without killing ourselves. The distance from the sun is just right. The tilt of the earth is just right. The distance from the earth to the moon, the size of the moon, the size of the Earth, the composition of the air: just right. So many examples of rightness.
Design and purpose are evidence of a creator. Is it reasonable that all of this complexity just happened on its own? I’m simply making a case. It’s up to you to decide what you believe. I believe that nature screams out that God is with us. What about you?
