An incredible new technology enables the transmission of text on a worldwide basis. It rapidly reduces production and distribution costs and for the first time allows large numbers of people to access text and pictures in their own homes.
The invention of 'movable type' by Gutenberg – the printing press.
The digital revolution is bringing about a similar huge change in evangelism, Christian discipleship and community, in ways which are only just beginning.
Print, video, radio and TV are mainly 'push' mediums, sending out a consecutive ('linear') prepared message, usually only to a single area of the world.
The Web is a 'pull' medium. It pulls in visitors on the basis of a defined interest. It is global: anyone, anywhere - in China or the Middle East - can find a page in seconds.
Unique property of the Internet is interactivity. Build 'community' around a website helps people feel wanted and that their opinions are valued. It gives them a place where they can ask questions in a safe way, when perhaps they would not do that face-to-face. Interaction is very important. Very few people become Christians just by reading something.
TV is not just radio with pictures. Print is not just speech written down.The Web should not be seen as just another way of delivering tracts or sermons. It is a revolutionary medium which can be used for evangelism if we 'work with the grain' of an interactive medium where the user is in control.
