Have you ever known of a young adult (18-early twenties) who drank often times and never once got merry while consuming alcohol?
I personally have known hundreds of alcohol drinkers in my time and have NEVER found one who did not get merry most of the time.
"Responsible drinking" is a lie from the pit of hell. It does not exist. It is a fairy tale of wishful idealism.
You are presenting something that just ain't never going to happen.
Ann is the only exception that I have ever encountered although I do not know her personally and have never been around her while she was drinking scotch and other mixed drinks. Now she testifies that she has drank many of these drinks and has never felt the effects of the alcohol. If she can drink down a glass of scotch having 20% alcohol content in it and not feel any effect from the alcohol then she is not the norm found in society. But I take her at her word, she is a huge exception though.
One beer with 4% alcohol in it and I can feel it working and I weigh 200 pounds.
Still, this argument is further descending into "this is my experience, so I demand this out of everyone." It doesn't work that way.
And when do we stop? If we shouldn't drink occasionally to relax or because we enjoy it, should we not take medicine that alters our mood, mental status, etc? Is caffeine out, because it is a highly addictive, mind-altering drug. What about anti-depressants for people with serious depressive and mood disorders? Where does it stop?
Of course, the answer to those questions above are issues of conscience. Some of the same Christians who are worried sick about alcohol use were the ones concerned that medicinal products weren't appropriate for use, either. There are people who take this to that extreme.
It is obvious that Christianity is a relationship in which the Spirit's work is done in your life. Behavioral modifications are necessary, but they are done in response to the conviction and leading of the Spirit. Since alcohol is not contrary to the letter and spirit of the Bible, this is an area where each has to earnestly seek the Spirit's guidance, not follow the legalistic, prescriptive and moralistic rationalizations of other people.
For me, this isn't a moral rationalization. I'm not swayed by hypothetical questions about my children, of which I don't currently have any, my witness, which has not been damaged by an occasional drink, or the struggles of other people. Giving me old recycled stories from pulpits of prohibition supporters is not going to sway me. I pray, listen to the voice of the Spirit, asking for guidance, and follow its leading. That is what I do for myself, and it's all I can ask of other people.
Blessings.
