Christians:If prophet John doesnt drink wine it becomes a sign of moral?

Just because John doesn't drink doesn't mean it is wrong for everyone to drink. Ok...Most Christians feel that drinking at all is a sin. I am a Christian. I don't believe that way. I believe to do ANYTHING in excess is the sin. This includes drinking, eating, even exercising...lol...Anything that you over do. Drinking strong drink or fermented drink is not the sin it is getting drunk off the drink that is the sin. Most Christians also feel that the wine Jesus changed from water was unfirmented. (grape juice) I don't believe this. Anyway, each person believes the way they want so, it doesn't matter. The only thing that matters is to believe that Jesus lived a sinless life and died on the cross for our sins and then was raised again on the 3rd day and lives forever. All we have to do is accept him and we can be saved.
