I find no scriptural basis to advocate 100% abstinance from all drinks containing alcohol.
That said, I find it 100% wise to abstain from the use of alcoholic beverages in today's society apart from medical purposes.
This is because I've seen how ugly alcoholism can be. I can recall being grossly abused as a young child by people under the influence of alcohol. I've watched alcoholics destroy themselves and their families. A few years ago I was attacked by an alcoholic on a binge and left with a torn shoulder and a detached retina defending him from entering my apartment and going after my children.
I find it rare to find someone who claims to only drink alcohol in small amounts socially to be truthful about it. I ended up coming to know one person from online pretty well in real life, one who had done much research to prove that it is okay to drink alcohol medicinally and claimed only to do so. Then in real life, I found she drank "medicinally" on a very regular basis and was a real witch when she went without.
When living in alcoholism central (Alaska) I was pretty shocked by the number of alcoholics. It is an ugly, ugly, ugly thing.
And nobody who is a believer in just a drink or two starts out with the intention of drinking past their limit. Nobody starts out with the intention of becoming addicted.
In my much younger years, prior to wanting to live for Christ, I thought alcohol was just wonderful. It wasn't so wonderful when I ended up in the hospital detoxing.
From what I've experienced with drinking in my youth and from what people did to me when drunk in both my childhood and even as recent as a few years back, from seeing the ugliness this stuff brings on, I find it in no way, shape, or form something that anyone should want to find a reason to use for anything other than true medicinal purposes. But even that...a few years ago I would buy it and drink one serving for pain to replace a narcotic medication my doctor ordered. I did so because I knew that the narcotic would stay in my system for 48 hours and it would be illegal for me to drive if I took it and I had three kids to drive around, so when things got bad I would have that one drink a couple hours before bedtime and be fine in the morning to drive.
I won't even do that anymore. The very thought of it after all I've seen and been through just makes me sick and it also causes others to doubt. That's not worth it.
Now if Christ himself comes down and offers it...well guess what. I still wouldn't because I don't want it and I'm quite sure he would understand! I don't like the taste of wine anyhow, makes me gag. Chocolate liquor is another story and if it was Christ himself, I might oblige but I'm pretty sure he wasn't, isn't, and never will be into liquor. Haaaaaa
And if anyone wants to argue that fat people who eat bacon are sinning just as much, I've never been molested or had to defend myself against a fat person who had one too many slices. That argument is ridiculous.
