Within the Book of Ephesians the Apostle Paul teaches about living the life of a real Christian as apposed to living as a Christian in name only. How many Christians do you know who are not very serious about their life in Christ? Sadly, it seems like alot. It is true, fortunately, that Christians are not saved by perfect law keeping; rather, through the grace of Christ. Yet, does God want a fake Christian?
Paul speaks of drinking in the above passage. Now he does not say it is wrong to drink but he does say that one whose lifestyle is of drink when they are a Christian is ungodly. He says, basically, don't chose a lifestyle of anything other than Christ. In fact, fill yourself of the Holy Spirit by "addressing one another in psalms and hymns and spiritual songs, singing and making melody to the Lord with your heart, giving thanks always and for everything to God the Father in the name of our Lord Jesus Christ" (Ephesians 5: 19-20).
If this understanding is not sure for you, please read and study the Book of Ephesians in context from front to end and this teaching will become more and more clear.
