According to the Bible wine can mean unfermented,or fermented,grape juice,which I do not believe Jesus turned the wine in to fermented wine,but grape juice.
We should not do anything that is harmful to our body,and not healthy in the long run,for that would not be godly.
God says He tempts no person,but they are tempted when led away of their lust,which if God allowed us to drink a little alcohol,it could lead to more,and God knows how people act when they are drunk,it is not always a guarantee they will act correctly,which those things would be under the category of lust,for God created us to only go by our needs,food,clothing,and shelter,not catering to the flesh,in any other fashion.
God did not say you can kiss a woman you are not married to,but do not fornicate,or steal things less then 10 dollars,but not above that price,so God would not allow us to drink a little,but do not drink a lot,for if God allowed us a little it could lead to more,and God does not tempt any person,and being drunk,or high,where it impairs your judgment would not be right.
Pro 20:1 Wine is a mocker, strong drink is raging: and whosoever is deceived thereby is not wise.
Pro 23:29 Who hath woe? who hath sorrow? who hath contentions? who hath babbling? who hath wounds without cause? who hath redness of eyes?
Pro 23:30 They that tarry long at the wine; they that go to seek mixed wine.
Pro 23:31 Look not thou upon the wine when it is red, when it giveth his colour in the cup, when it moveth itself aright.
Pro 23:32 At the last it biteth like a serpent, and stingeth like an adder.
Pro 23:33 Thine eyes shall behold strange women, and thine heart shall utter perverse things.
Pro 23:34 Yea, thou shalt be as he that lieth down in the midst of the sea, or as he that lieth upon the top of a mast.
Pro 23:35 They have stricken me, shalt thou say, and I was not sick; they have beaten me, and I felt it not: when shall I awake? I will seek it yet again.
At least it appears to me that God does not want us to drink alcohol,and the Bible calls the grape juice,wine,before it ferments.
Now somebody might get away with saying God does not care if we have a little alcohol,but do not be drunk,but common sense would tell you,that it is a temptation that they might drink more if allowed to drink a little bit,that could lead to being drunk,and you know the commercial,nobody can only eat one Lay's potato chip.
It could be God allows a little wine,which I believe would be naturally fermented grape juice,without the tampering of people,but it still does not seem right to me,and does not make sense.
