I don't think you are correct, that they didn't know how to preserve Grape Juice.
"And he drank of the wine, and was drunken; and he was uncovered within his tent." Genesis 9:21.
"wine" in Genesis 9:21 from the Strongs H3196 = "From an unused root meaning to effervesce; wine (as fermented); by implication intoxication: - banqueting, wine, wine [-bibber]."
"Therefore God give thee of the dew of heaven, and the fatness of the earth, and plenty of corn and wine: Genesis 27:28.
"wine" in Genesis 27:28 from the Strongs H3423 in the sense of expulsion; must or fresh grape juice (as just squeezed out); by implication (rarely) fermented wine: - (new, sweet) wine.
Way back in Genesis, they had grape juice. If they didn't have a way of preserving it, then they were only supposed to drink it when it was fresh. Either way, they were not supposed to use fermented wine.
As Christians, "all things in moderation...just not in excess" is NOT a good motto. Do you think it is OK to use Cocaine in moderation? or Opium? Alcohol is just another drug... The motto for Christians should be, "all GOOD things in moderation...and do not touch the things that are unhealthy."
We'll just have to agree to disagree on the whole "grape juice" thing, as I said it was fully discussed and explored in another thread, I'd post it for you, but I'm afraid I can't find it, but your right about one thing though unless it the grape juice/which ferments and turns into alcololic wine when stored, unless you drank the freshly squeezed grape juice, right away (that day) it would by nature, start fermenting and turning into alcoholic wine...
You can make almost any fruit or vegetable or grains or any kind of organic material (foliage) "ferment" and you can then squeeze out the juice and make an alcoholic beverage out of it, but fruit ferments (rots) the quickest, and fermented grapes tasted very good, so that's what they usually did. The production of alcoholic beverages is very ancient, and small amounts of alcohol can actually be good for your health (as I said "small" amounts) Also, the alcoholic beverages were safer to drink than most of the water available, and so, in ancient times fermenting grapes or other fruits and such, was seen as a way of actually purifying a drink/water (better and safer than water).
Even if they did have the ability (technology) to prevent stored and sealed fruit juices from fermenting (which in the other thread I'm talking about, the general concensus was that they didn't) But even if they could, they usually didn't (wouldn't bother)
As to my comment "All things in moderation" I didn't mean hard, illegal drugs. I believe that any narcotic, drug, or controlled substance should be overseen and advised or not advised (controlled) by a medical doctor, and if an M.D. sees fit to prescribe heavy drugs (substances) for purely medical reasons only, that could potentially be abused, then they should be the judges to evaluate, discern and oversee and see that the substance is used in moderation (as prescribed) and it is their job to evaluate whether or not their patients are using the substance responsibly...
My Grandfather, in his old age, and with his heart problems was actually told by his doctor that he should drink two glasses of alcoholic red grape wine for his heart, circulation and other health problems, if I had it my way, I would make every mind altering drug/substance illegal recreationally, and would make all substances medically legal, overseen by your M.D. (for psyhical health reasons) or by your professional Psychologist (if for mental health reasons) And if you have valid medical reasons, you Doctors should be open to prescribing it to you.
As I said "small" doses of alcoholic beverages can be good for your health, (and you might therefore, be able to convince your doctor about having one or two a day, but not to excess. As for cocaine, heroin, meth, I see very little health benefits to these (but some could be argued, in particular cases) And as I said, if one of these users wan't to try and make their case before their M.D. or Psychologist, then the decision is in the professionals hands, not the patients.
Doctors prescribe hard, heavy mind altering substances (drugs) all the time, but what the Doctors must realize is that along with being a Doctor, they are also a judge, a judge as to discussing with their patients whether or not they have true medical needs and valid reasons for taking such substances. Doctors prescribe (all the time) oftentimes synthetic pill forms of some of the most powerful drugs (substances) on earth, all the time, to those with valid medical reasons, and that's the way it should be, (in my opinion) They prescribe synthetic versions of some of the most abused substances on earth...
"Methadone" synthetic meth, is just one example, and there are many, many others, just can't think of them right now. The Doctor, along with being a Doctor and judge, also becomes a babysitter, to make sure the drug is taken only as prescribed and is not being abused or overused by the patient for the purposes of getting high, instead of taking only the controlled amount to manage pain or other medical reasons, regular checkups and developing personal close relationships with their patients by actually taking the time to talk with them, instead of the assembly line health care system we seem to have now, would help greatly in/with this...
Doctors and health care professionals have a tough job, I only hope their up to the task...
Well, those are my opinions, in Jesus name, God Bless!
