Not insider, not outsider, but dualsider.
I.e. someone who is both an insider and outsider, or someone who is neither inside nor outside, but dualside.
Predicting the next missiological buzzword. Remember, you heard it here first. ;-)
There are certain paradigms of witness to Muslims that treat Islam as an evil, monolithic entity that corrupts everything it touches. Therefore, in this view, when talking about evangelism/discipleship, we should have nothing to do with “Islam.”
The tendency to binary thinking is related to a modern worldview and a naïve realism epistemology. This black and white paradigm also understands theology of religions to mean that Christianity is against Islam and will eventually triumph. There can be no mixing between the Christianity and anything else.
This is fallacious and lazy thinking. See this post by Daniels: Black and White - - or not?. We could easily expose this fallacy by discussing the incarnation and the nature of biblical revelation, but I want to make one quick point… Ironically, this model of missiology also mirrors conservative Islamic law, where everything is either haram or halal. It has a lot to do with with how mainstream Muslims view the world today!
