I am seeking to understand whether my theological views align with the current understanding of the second law of thermodynamics. As a physicalist, I believe that all ontological existents consist of spatiotemporal "bodies" and their positive attributes. Consequently, I hold that nothing exists in the universe beyond matter and energy, which originate and annihilate in succession (see this entry and this video for more on my theological physicalism). My view includes the belief that the afterlife is a physical system within a finite volume where Paradise endures eternally, allowing for unending blessings to its inhabitants.
However, the second law of thermodynamics states that the entropy of an isolated system within a fixed volume increases and never decreases, leading all such systems to eventually reach heat equilibrium, thereby eliminating ordered systems. To reconcile this, one might suggest that the second law allows for a decrease in entropy but typically sees an increase.
My question is: Does the current understanding of the second law of thermodynamics categorically state that it is physically impossible for the entropy of an isolated system to decrease, similar to how the first law prohibits the creation of matter or energy from nothing? Or does it simply assert that entropy usually increases, making a decrease extremely unlikely but not physically impossible?
Also, is it technically possible for a set of simultaneous and highly coordinated quantum mechanical effects to cause the entire isolated system's entropy to decrease? If this is merely extremely improbable but not physically impossible, then the difficulty would seem to go away, since the process could technically be actualized by God given His omnipotence.
[Note: The first part of my question has been addressed here, but not the second part of my question. I am specifically interested in whether our current understanding of the laws of physics allows for a mechanism through which a physical system in the form of an ordered residence may endure forever.]
