Jesus, or from my understanding, the Bible does not forbid alcohol, but it does warn against drunkeness!
I do enjoy a couple of pints with my friends, or a glass or two of wine with my family, and see no problem with this, but I am aware of the scriptures that discuss drunkeness, and therefore avoid the temptation to have 'one too many' - when we are drunk, I think our judgement and mind can be slightly altered and we are more open to temptations and doing, or saying something without first thinking it through, which in itself could lead to sin!
Alcohol addiction is a different matter all together, as is any addiction, for addiction is something that comes first in our lives and become idols, and this kind of addiction not only includes things like alcohol, but the lowley cigarette, the bar of chocolate, the spending excessively through need, addiction or deep rooted desire, so it think we need to be careful and guard ourself against such things!
