Imagine a reaction vessel in which we have H2O, O2 and an infinite number of possible configurations of carbon-based compounds. The reaction is kept in the perfect conditions for the formation of amino acid compounds. Let the reaction progress until the amino acids have bonded together to form chains called proteins. Through probability alone, this reaction will eventually give birth to a particular protein called deoxyribonucleic acid, or DNA for short; life has been created.

Our identity is defined by our genetic sequence. It dictates every one of our characteristics; it is our mind and our body. The genetic code of an organism is the representation of it's identiity on a microscopic, chemical scale. It defines who we are. It is life.

It is also a chemical reaction, the oxidation of carbohydrates is used as an energy source to trigger a reaction called mitosis where the genetic code reproduces itself. This is DNA's sole mission, to duplicate itself, to propagate. Simply put, all organic life has at its core of its being, at the lowest common denominator, the sole purpose of sustaining life. It is a self-sufficient chemical chain reaction. From a chemical point of view, it's all here for the same reason, to grow.

To damage life, to destroy it, is to deny it's very nature. To nurture it, to ensure its continued existence, is it's inherent driving force. All life is constructive in nature. This strongly suggests that we humans, as carbon based life forms have a constructive, creative nature. To deny this, to destroy life, is to deny the nature of what defines you as part of nature itself.

If God created us in his image, then DNA, our "blueprint" is his photograph. He created something that has ingrained in it's identity a positive nature. Life, nature, and consequently humanity has as its core an inability to destroy, it knows only growth. It knows only a positive direction of change, not a negative direction. This positive force fulfills its purpose through growth in every direction; be it physical, cognitive or spiritual in nature.
