I was challenging the op which seemed to be saying that drinking alcohol is a sin, therefore Jesus turned water into, and drank only, grape juice.
Well, I do not believe drinking strong alcoholic beverages (moderately with a meal) is a sin for a New Testament saint. However, this would have been a sin for the Old Testament saint, though; For they had strict rules even on what kind of animals they could eat. Proverbs 23:31-32 says, "Look not thou upon the wine when it is red, when it giveth his colour in the cup,
when it moveth itself aright. At the last it biteth like a serpent, and stingeth like an adder."
I am an Abstentionist and not a Prohibitionist. This means that while certain believers in Christ (under the New Covenant) do have a liberty in Christ to drink strong alcoholic beverages soberly, and so as not to make their brother to stumble, I encourage all believers to consider the facts of alcohol in how it destroys the body; Therefore, I encourage (not command them) that they should abstain from it out of love for their Lord, their temple, and others. For while it may be lawful, it is not always profitable. For alcohol can lead to addiction, drunkenness, and in causing great pain upon others, etc. For it may be lawful for you to play with spitting cobras, but it simply would not be wise or profitable.
I believe there are 3 types of wines mentioned in the Bible.
#1. Fermented Wine (Strong in alcoholic content).
#2. Fermented Wine Diluted by Water (Low in alcoholic content)
#3. Unfermented Wine or Freshly Squeezed Grape Juice (A non intoxicating beverage).
I believe the wine during Bible times that the Old Testament saints drank was Wine Type #2, whereby it was a wine mixed with water and was lower in alcoholic content (Which was the wine seen at the Wedding of Cana before Christ made Wine Type #3, which was non intoxicating grape juice or unfermented wine); In other words, the wines commonly drank by the OT saints was not like the strong wines of today; And Jesus made grape juice that made was considered the “best wine.” Wines of today (By wine tasters) are considered the best by their taste and not how much they can intoxicate you.
Wine mixed (diluted) with Water Verses:
Revelation 14:10 says,
“The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb”
(Contrast this with Psalms 75:8)
1 Timothy 5:23 says,
"Drink no longer water, but use a little wine for thy stomach's sake and thine often infirmities."
Proverbs 9:2 (NIV) says,
"She has prepared her meat and mixed her wine; she has also set her table."
Proverbs 23:31 - Do not look at wine when it is red.
John 19:34 - Blood and water mingled together from Christ's side; And Scripture essentially says the wine in the Lord's supper is representative of Jesus's blood (See Matthew 26:27-29).
Isaiah 1:22 (NIV) says,
“Your silver has become dross, your choice wine is diluted with water.”
Pure silver, which would be too soft to be durable, is mixed with 5-20% copper in an alloy known as sterling silver.
How silver is made - material, making, history, used, processing, industry
If one were to take note: One has to mix copper in silver in order for it to be durable so as to be used. Just as one must use water in their mixture of wine to use it.
So the idea here is that the silver (mixed with copper) they use has become so dross (or watered down it is then cheap. Just as the wine (mixed with water) is diluted even more whereby it is cheap wine (for the times).
Wine could be carried in an undiluted state within leather skin like bottles and then later mixed with water for use. Timothy was told to use a little wine in his water because of the infirmities in his stomach. Paul was telling him to use Biblical wine so as to resolve a medical issue.
