“For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.” Romans 1:20
One of my favorite college courses was Thermodynamics. It was my strongest science class and–call me a geek–I still enjoy reading books on the stuff when I can. One of the coolest parts of science is discovering how God reveals Himself through His creation.
The Trinity is one of the most difficult concepts of the Christian faith, (just check out Barth). There are tons of analogies and models people use to try and comprehend this unity in diversity. Without a doubt, the one model that makes the most sense is found in what thermodynamicists call “The Triple Point“.
In simple terms, the Triple Point is when the Temperature and Pressure conditions are in perfect balance so that a substance can exist simultaneously in all three phases. For example, water exists in one of three primary phases; solid, liquid or gas. But when the temperature and pressure are just right, water can be a solid, a liquid and a gas at the exact same time. Here is a simple graphic illustration of the Triple Point.
Triple Point is the coexistence of all three phases in perfect equilibrium.
For me, the Triple Point is a beautiful picture of YHWH who exists in the balance of Time and Eternity as Father, Son and Spirit–each one with a unique phase, yet each one existing in perfect equilibrium that cannot be divided–one from the other.
Even if understanding the Triple Point does not answer every question about the Trinity of YHWH, it should at least demonstrate the possibility of the diversity in unity that is God.
