# What I Found

Atheists will sometimes ask what it would take for a Christian to walk away from Christianity. I think Paul addressed that in his letter to the Corinthians when he stated that if Jesus was not raised from the dead (i.e. bodily, as an actual historical event occurring in space and time), then our faith is in vain, we are to be most pitied of all men, and we should abandon this then-false religion, for we would be false witnesses against God by saying God raised Jesus from the dead if He didn’t [1Cor 15:14-19]. This emphasis on actual, objective, historical events that could be investigated is a really bad way to start a false religion, but a great way to proclaim truth. Per the apostle Paul, Christianity stands or falls with the Resurrection.However, an atheist probably would not be content with a Christian leaving Christianity simply to turn to Judaism.  For, of course, refuting Christianity would still not eliminate the need for God. But the desire, nonetheless, is still for us to leave all religion and join their atheist ranks. So that got me thinking: what have I found in Christianity that I would be leaving if I were to oblige the atheist missionary? Well….

I have found Aristotle’s Unmoved Mover[1]; Aquinas’ First Cause[2]; the “Highest Good” that the ancient philosophers sought for; Anselm’s “that than which nothing greater can be conceived” [3]; the Necessary Being upon which all else depends for existence; the Fine-tuner of the universe that explains the Goldilocks dilemma we face when we examine the universe; the Enabler of abiogenesis, without whom life cannot come from non-life; the Source of all the information we find encoded in our own DNA; the Designer behind all the “apparent design” in biology that frustrates Richard Dawkins; the Mind that explains the consciousness of our minds that scientists can’t explain; the Truth that explains objective transcendent truth [Jn 14:6]; Love that explains how and why we love [1Jn 4:19]; the Grand Artist that explains aesthetics[4] in what should be a cold, cruel, survival-focused universe; and the Author of life [Acts 3:14-15 ESV]. It would be intellectual suicide for me to give up all that. But the atheist is asking me to do far more than just drop an intellectual stance.

I have also found the One who loved me from before the beginning of time [Rom 5:8, 2Tim 1:9, Eph 1:4, 1Jn 4:9-10]; a perfect Father [Rom 8:15-16]; the Savior of my soul [Lk 2:11, Jn 4:42]; my Redeemer who rescued me [Ps 19:14, Job 19:25]; the One who made me in His image and gives me intrinsic value [Gen 1:27, Gen 9:6, Matt 6:26]; my Mediator before a just and holy God whom I could never satisfy in my sinfulness [1Tim 2:5]; my Counselor, Advocate, and Intercessor [Jn 16:7-14, Rom 8:26-27]; my source of freedom – truly beautiful, joyous freedom! – [Jn 8:32,36]; my Comforter in times of trouble [2Cor 1:3-5]; the delight of my heart [Ps 35:9]; my Peace when all around me is turmoil [Jn 14:27, 2Thes 3:16]; my steadfast foundation in the tumultuous craziness of life [Lk 6:47-48]; my Hope of glory [Col 1:27];  and the Architect of my eternal home [Heb 11:10]. Yeah, I found all that, too.

Christianity is not simply a rational intellectual viewpoint, but a relationship with my Creator. It isn’t simply some sterile, isolated idea or opinion, but rather the very presence of my Creator. And you ask me to give up that relationship, and all those answers to life’s questions to boot, and be content with the loneliness and unanswered questions of atheism? Are you crazy?! Maybe, but I’m not!

# “I Fought the (2nd) Law & the Law Won”

No, today’s title doesn’t mean this post is about misremembered lyrics to 60’s songs. This is a different law, and one even harder to win against. Today, I want to review some basics of thermodynamics that point to the need for a nonmaterial, transcendent, first cause of the universe. This is a problem for atheists because the most reasonable candidate for that position is the God whose existence they deny. Let’s jump in.

The first and second laws of thermodynamics may be summarized as follows: 1) energy is neither created nor destroyed, but only changes form, and 2) the amount of usable energy in any closed system is always decreasing. The first deals with the quantity of energy, while the second deals with the quality of that energy. The measure of that decrease in usable energy is called entropy. A low-entropy system is highly ordered with much energy available to do work. A high-entropy system is approaching (or has reached) a state of uniform, random distribution, with little to no usable energy available. What does this have to do with anything? Let me quote from my college thermodynamics textbook:

Since no actual process is truly reversible, we can conclude that the net entropy change for any process that takes place is positive, and therefore the entropy of the universe, which can be considered to be an isolated system, is continuously increasing. … Entropy increase of the universe is a major concern not only to engineers but also to philosophers and theologians since entropy is viewed as a measure of the disorder  (or “mixed-up-ness”) in the universe.

$S_{gen} = \Delta S_{total} \begin{cases} >0 & \text{irreversible process}\\ = 0 &\text{reversible process}\\ < 0 & \text{impossible process} \end{cases}$

This relation serves as a criterion in determining whether a process is reversible, irreversible, or impossible.[1]

There’s a couple of relevant statements in that section. One is that the entropy of the universe is an issue for philosophers and theologians as well as engineers. The textbook author correctly realizes the implications of the 2nd Law. It has been our consistent observation that usable energy does not increase without a contribution from outside the system being studied. At best, it stays constant, like the idealized reversible process mentioned in the text (that doesn’t actually exist), but otherwise it’s always decreasing. And it can’t have been decreasing forever or the amount of usable energy in the universe would be exhausted already. This leads to the second noteworthy statement above:  the last case of the system entropy equation above defines what is an impossible process. Now, in science, we don’t take words like impossible lightly. This isn’t like watching a basketball game and seeing an “impossible” shot. No, this is more than just our typical hyperbole. If the universe is an isolated physical system that can never increase in total usable energy, and is clearly decreasing, then we have to recognize that there had to be a starting value. If the fuel tank of our universe is getting closer to “Empty”, there had to be a “Full” at one time. Things run down, disperse, and seek equilibrium, or their lowest energy state. We see this with our own sun, which should burn out in roughly 5 billion years.[2] And this is happening throughout our world, our solar system, our galaxy, our universe. Closer to home, this irreversible dispersal of energy is also why we have to keep our coffee cup on a warmer to keep it from equalizing to room temperature; it’s why we have to do preventative maintenance to keep our equipment from rusting if it’s exposed to the environment; it’s why perpetual motion machines are simply not possible.[3] Consider how bluntly Sir Arthur Eddington, the astronomer who first observationally confirmed Einstein’s theory of relativity, put it:

The Law that entropy increases—the Second Law of Thermodynamics—holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell’s equations— then so much for Maxwell’s equations. If it is found to be contradicted by observation— well, these experiments do bungle things sometimes. But if your theory is found to be against the Second Law of Thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation[4]

Now, perhaps you might say that that initial description of the universe as an isolated system is rendered inaccurate by the existence of a multiverse. Although completely unsupported by any scientific observation, and believed to be beyond the ability to ever observe by our event horizon, the multiverse is a popular escape for many – a kind of magic place where anything is possible.[5] Well, that might make our universe an open system briefly, until you simply label the multiverse as your isolated system, with our universe being one subsystem and the surroundings – i.e. the rest of the multiverse – being another subsystem in the arbitrary isolated system. So, appealing to the multiverse to get around the 2nd law doesn’t really help.

Maybe there is an escape in the idea of a cyclical universe that recycles itself. Consider then this statement from Alexander Vilenkin:

It is said that an argument is what convinces reasonable men and a proof is what it takes to convince even an unreasonable man. With the proof now in place, cosmologists can no longer hide behind the possibility of a past-eternal universe. There is no escape, they have to face the problem of a cosmic beginning.[6]

But what are we to do if there is a definite beginning to the universe and it can’t simply have existed eternally? Things always require a cause outside of themselves to come into existence. And that’s what worries atheist scientists. When you’re talking about all of our physical reality, what’s outside of that? Nothing according to a materialistic worldview. And so their presuppositions actually make them close-minded to viable options – options that match up with our daily commonsense observations: basic cause and effect, that things don’t simply pop into existence for no reason, that things running down can’t be running down forever. The Second Law reminds us of our finitude [Is 51:6], the existence of a beginning [Gen 1:1], and by implication, the need for a Beginner. And the Second Law… always wins. Take care 🙂
