Let me provide what I consider to be a significant piece of evidence for the truth of Christian theism.
It all begins with the Goldilocks Principle. Wikipedia describes it as follows:
The Goldilocks principle is named by analogy to the children’s story, The Three Bears, in which a little girl named Goldilocks tastes three different bowls of porridge, and she finds that she prefers porridge which is neither too hot nor too cold, but has just the right temperature.[1] Since the children’s story is well known across cultures, the concept of “just the right amount” is easily understood and is easily applied to a wide range of disciplines, including developmental psychology, biology,[2] economics and engineering.
What fascinates me is how well the Goldilocks principle describes life. Many are probably familiar with the use of the principle to detect other planets that could possibly support life:
In astrobiology, the Goldilocks zone refers to the habitable zone around a star. The Rare Earth Hypothesis uses the Goldilocks principle in the argument that a planet must neither be too far away from, nor too close to a star and galactic center to support life, while either extreme would result in a planet incapable of supporting life. Such a planet is colloquially called a “Goldilocks Planet”.
Yet what is often overlooked is that Life itself is built around the principle. In physiology, the central concept is something known as homeostasis. The dictionary defines it as follows:
the tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function.
The ability or tendency of an organism or a cell to maintain internal equilibrium by adjusting its physiological processes.
Wikipedia defines it as:
Homeostasis is the property of a system within an organism in which a variable, such as the concentration of a substance in solution, is actively regulated to remain very nearly constant.[1] Examples of homeostasis include the regulation of body temperature, the pH of extracellular fluid, or the concentrations of sodium, potassium and calcium ions, as well as that of glucose in the blood plasma, despite changes in the environment, diet, or level of activity. Each of these variables is controlled by a separate regulator or homeostatic mechanism, which, together, maintain life.
Now note this – homeostasis, which is near the very essence of life, is basically the Goldilocks Principle. Think of it this way – you don’t want your blood pressure to be too high. But you also don’t want it to be too low. The body is built to correct for each extreme. The same would true for just about every aspect of your body. Blood sugar? Not too high and not too low. Heart rate? Not too high and not too low. White blood cell count? Not too high and not too low. On and on it goes. And it even extends into the very workings of your cells. For example, there are rather clever mechanisms within your cells to ensure that the intracellular iron levels are not too high (which would generate toxic free radicals) but not too low (which would disable important metabolic enzymes).
In fact, a violation of the Goldilocks principle is typically linked to disease. Eat too much and experience obesity. Eat too little and experience malnutrition. Put too much stress on a joint and watch it tear. Put too little stress on a joint and watch it atrophy. And when something goes wrong in the body? It’s typically because the Goldilocks principle has been disabled somewhere. Too much thyroid hormone? It could be Graves Disease. Too little thyroid hormone? Could be a goiter.
What I am pointing out here is not controversial; it is well known that homeostasis is a defining feature of life. All I am adding is that homeostasis is essentially the same as the Goldilocks principle.
What does Christian theism have to do with any of this?
