Entropy — the second law of thermodynamics — states that in any closed system, disorder increases over time. Energy disperses, structures decay, and everything moves toward equilibrium. It is the reason stars burn out, food spoils, and bodies age. The question of whether entropy existed before the Fall is one of the more fascinating intersections of theology and physics, and Christians hold genuinely different positions on it.
What Entropy Is
The second law of thermodynamics is one of the most well-established principles in all of science. It describes a universal tendency: ordered systems become disordered over time unless energy is continually added. A hot cup of coffee cools. A house left unattended deteriorates. A living body, deprived of food and oxygen, dies.
Entropy is not inherently destructive — it is a feature of how energy works in the physical universe. Many natural processes that we consider good depend on entropy: digestion, weather patterns, even the nuclear reactions that power the sun. Without entropy, the universe as we know it could not function.
The Fall and Death
📖 Genesis 3:19 The Bible links Death directly to the Fall:
By the sweat of your face you shall eat bread, till you return to the ground, for out of it you were taken; for you are dust, and to dust you shall return.
Paul reinforces this in Romans 5:12: "Sin came into the world through one man, and death through sin." The theological claim is clear — death is a consequence of human rebellion, not part of God's original design.
The question is whether "death" here refers to all physical decay (including entropy) or specifically to human spiritual and physical death. This is where Christians diverge.
View 1: No Entropy Before the Fall
Some Christians — particularly those in the young-earth creation tradition — argue that the second law of thermodynamics was introduced or activated at the Fall. Before sin, the Garden of Eden operated under different physical conditions. There was no decay, no death, no running down of systems. The Curse fundamentally altered the physics of the universe.
This view takes the "very good" of Genesis 1:31 to mean a world without any form of deterioration. It sees entropy as part of the curse — a physical expression of the spiritual corruption introduced by sin.
View 2: Entropy Is Part of Good Design
Other Christians — including many old-earth creationists and scientists — argue that entropy is not a curse but a feature of how God designed the physical world. The second law of thermodynamics is necessary for life: metabolism, energy transfer, and even thought itself depend on entropic processes. A universe without entropy would be static and lifeless.
In this view, what the Fall introduced was not entropy itself but a distortion of it — specifically, human death, spiritual separation from God, and the subjection of creation to "futility" as Paul describes in Romans 8. The physical laws remained the same; what changed was humanity's relationship to them and to God.
Creation Subjected to Futility
📖 Romans 8:20-21 Paul's language is carefully chosen:
For the creation was subjected to futility, not willingly, but because of him who subjected it, in hope that the creation itself will be set free from its bondage to corruption.
"Futility" and "bondage to corruption" could describe entropy in its destructive aspect — the tendency of things to break down and die. But Paul also says this subjection was done "in hope," implying it is temporary and purposeful, not simply punitive.
The New Creation
📖 Revelation 21:4 Whatever role entropy plays in the current world, the Bible is clear about its endpoint:
He will wipe away every tear from their eyes, and Death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.
The new creation will operate under different conditions. Whether that means the abolition of entropy or its transformation into something entirely good is not specified. But the trajectory of Scripture moves from a world marked by decay toward one marked by permanent, unfading life.
What This Means
The relationship between entropy and the Fall is a secondary theological question — important for scientific and philosophical discussion but not essential to the gospel. What is essential is this: death is an enemy, not a friend. The world is broken, not functioning as designed. And God's plan, from Genesis to Revelation, is to restore everything that the Curse corrupted — including, ultimately, the very fabric of creation itself.
