Here are two 'must read' links if you want to be up with what people are thinking. The first is a survey that was done of evangelical leaders who attended the Lausanne Conference in Cape Town last year. It gives all sorts of information regarding what 'evangelical' leaders are thinking and is cool because it covers leaders from across the globe. It is a Pew Forum survey.
The other is put out by the World Council of Churches and is guidelines for Christian mission work - how to be effectively Christian without treading on the toes of the other faiths. Christian Witness Recommendations.
