keller on contextualisation

"Everyone contextualizes — but few think much about how they are doing it. We should not only contextualize but also think about how we do it. We must make our contextualization processes visible, and then intentional, to ourselves and to others.
We must avoid turning off listeners because we are culturally offensive rather than the gospel.
Active contextualization involves a three-part process: entering the culture, challenging the culture, and then appealing to the listeners.It involves learning to express people’s hopes, objections, fears, and beliefs so well that they feel as though they could not express them better themselves.

If we are living in the culture and developing friendships with people, contextualization should be natural and organic. It will simply bubble up from the relationships in our lives and in our pastoral ministry."
