The “News and Notes” section of our fourth-quarter 2025 Does God Exist journal included an item about the Cana wedding feast where Jesus turned water into wine (John 2:1-11). Our skeptic friends have been quick to challenge this biblical event, claiming it is impossible from a chemical standpoint. John Lankford, a chemistry teacher in Fort Smith, Arkansas, and supporter of this ministry, sent the following comment on the matter:
In the last journal, you addressed this event of “water into wine.” While teaching AP chemistry, a student asked me, “Wouldn’t H2O changing into all the organics needed for flavoring require a nuclear event?” I explained a POSSIBLE scenario to the class.
Since we don’t know many details of the event, we can logically SPECULATE some things. First, the “water” was not pure (a misnomer itself) but contained gases like carbon dioxide and oxygen. So, all the basic atoms were in the water. In fact, CO2 + H2O + energy —> a sugar + O2. So, no nuclear reaction is needed to get carbon for grape sugars or flavorings. But an external energy and organizational force is required (which was Jesus, the Word). The oxygen, as a by-product, could give the “wine” a “bubbly effect” that might enhance the taste (similar to how people buy “oxygenated water” today).
This, of course, is just SPECULATION, but basic FACTS about ancient waters and the chemical reaction we see in photosynthesis suggest that Jesus called into play what was already available in nature to perform a miracle. (PS-even the assumed clay jar may have acted as a catalyst). The fact that a miracle can have a “mechanism” does not negate its being a miracle.
At any rate, this SUPPOSITION lets the student know that a “nuclear reaction” need not be what “must happen.”
Thanks to John for his explanation of the water into wine miracle from a chemistry teacher’s perspective.
