Galations 5: 19-22
Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality, 20 idolatry, sorcery, enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, 21 envying, drunkenness, carousing, and things like these, of which I forewarn you, just as I have forewarned you, that those who practice such things will not inherit the kingdom of God.
Romans 14
21 It is good not to eat meat or to drink wine, or to do anything by which your brother stumbles.
My husband and I have an occasional drink at dinner and see nothing sinful about it. But, if I'm around a friend or family member that does not believe in drinking, I will not drink because it could offend them and we are not to offend our brothers and sisters in Christ or if I'm around someone with a drinking problem, I won't drink.
If drinking becomes a way of life or something I just can't live without or something I must have to have a good time, then something is wrong. I believe the same thing many posters stated: moderation is key. We also need to remember that our body is the temple of God and needs to be clean for him.
