I don't Twitter (or is it tweet?).  But I can't claim total purity, since I have facebook, myspace, and I blog.  Still, I've been purposefully avoiding the Tweet scene because it seemed to me to represent the worst of the other three.  No genuine conversation or community whatsoever, just an endless flow of (mostly trivial) information. 

I may rethink this position.  Not only did Abraham Piper point out that a narcissist is a narcissist regardless of where he is or how he spreads his narcissism (i.e. the powers of Twitter can be used for both good and evil, it all depends on the person), but the boys at Middlebrow (the podcast of Scriptorium Daily) have brought up a point worth considering:  If Christians are called to witness to the world and bring the gospel to the marketplace, and our marketplace is Twitter, isn't that exactly where we should go? 

It certainly is.  Christians who avoid new technologies and cultural trends altogether are not paying attention to the book of Acts.  Meeting unbelievers where they are and speaking their language is essential to evangelism.  But there's a danger lurking.  I would not be the least bit surprised to hear someone advocating "Twitter church" pretty soon.  This would be nothing new, of course.  Evangelicals have been advocating a move away from traditional church structures to private religion for years.  The point is that God knows what he's doing, and it's not up to us to decide to change the rules of the game. 

Dr. Reynolds has noted that Christianity is a religion of a book, not a movie.  This means that, however good it is that we are becoming more and more video literate as a culture, we can't allow our normal literacy to decline, because God isn't likely to send us an inspired DVD any time soon.  As a Christian, being video literate is important for witnessing to a video culture, but we can't allow ourselves to lose the ability to read and interpret a written text.  If we do, we will lose our only direct tie to the foundation of Christianity itself, the Word of God.

Likewise, Tweeting is not preaching.  In the Old Testament, the Word of God was delivered to messengers called Prophets, who personally and incarnationally brought that Word to the people.  In the Apostolic age, the Word was made flesh and the gospel of that Word was delivered by the Apostles through preaching.  It is in hearing the preached Word that God has promised to meet his people, to create and increase faith, and to seal believers with the Holy Spirit.  This simply can't happen on Twitter.

Just as we need to become more video literatre while not losing our ability to read and understand written texts, we must be careful not to let our increased Twitteracy diminish our ability to engange in genuine communication with real people in real community.  The more we retreat into Twitter and other online communites, the less at home we will feel in true, physical communities (such as church).  The body of Christ, like the Son of God Himself, is incarnational.
