One thing I have learnt is that even if you don't agree with something we are all sinners and everyone messes up sometimes at many times in life as a christian and before you became one too. Therefore don't judge, pray, be a friend try and understand why. I don't drink, I don't think it is a good witness as a christian to drink, I think alcohol is over-rated, no alcohol tastes as good as a Dr.Pepper, a strawberry milkshake, cool blue raspbery Gatorade or an ice-cold glass of juice.
I use to drink, I use to drink a lot, I use to drink so much I don't remember certian years of my young life and have had to play catch up for years as having destroyed my high school education as a result. I just can't drink I'm highly addicted to alcohol, I know I tried drinking again in a bad stage in my life it was a big mistake, but thats long gone now. Some christians believe all alcohol is wrong and some believe instances where alcohol was drunk in the Bible it was not fermented meaning I believe it wasn't alcoholic, now I don't know about that, I don't know anything about wine making or am I sufficiently knowledgeable to be able to determine whether its is possible to know if the wine drank in scripture was alcoholic. What I do know it destroys lives. Kids at school only 11 are getting regularly waisted every weekend. Alcohol is the acceptable drug, but it destroys so many lives, wastes so many lives, costs huge amounts in health care. I know it can be drunk responsibly, and I don't judge other christians for drinking afterall I'd be the biggest hyopcrite if I did, but I believe the world would be a better place without it.
