I am an IFB, and I am VERY much against gambling and drinking, especially drinking. Before I got saved, I was against alcohol of ANY kind or amount, and now I'm even more against it. Yes, the Bible doesn't say you can't have ANY at all; however, it does say not to get drunk with wine.
"Wine is a mocker, strong drink is raging, and whosoever is deceieved thereby is not wise." -Proberbs 20:1
"And be not drunk with wine, wherein is excess, but be filled with the spirit." -Ephesians 5:18
Although the Bible doesn't necessairly say there's anything wrong with drinking in moderation, I prefer to not drink at all- not even a SIP. I don't want to start a habit of drinking just a little, and have it give way to drinking a lot, and then not be able to stop myself.
