Is drinking necessarily bad?  I go to restaurants and grocery stores that sell alcohol.
		
		
	 
Eph. 5:18 says "Be not drunk with wine, wherein is excess, but be filled with the Spirit." 
I take that to mean that alcohol can be used as long as we refrain from becoming drunk. I've personally known a LOT of people (mostly men and mostly family) who were seldom, if ever, sober. Drunks are generally very obnoxious. On rare occasions, a person (like my dad) will actually become a lot kinder with alcohol. My mother, who was a sweet and kind person when sober, became angry and impossible to deal with when she and my dad drank on Friday night. They both became the opposite of what they were like when sober.
Of course, our Christian testimony is very important, and we have to be careful how the world sees us and whether or not they will believe our testimony. If they see us staggering around, with slurred speech and being obnoxious from alcohol, trying to tell them about Christ will fall on deaf ears.
