'Contextualization is not - as is often argued - "giving people what they want to hear." Rather, it is giving people the Bible's answers, which they may not at all want to hear, to questions about life that people in their particular time and place are asking, in language and forms they can comprehend, and through appeals and arguments with force they can feel, even in they reject them.
Sound contextualisation means translating and adapting the communication and ministry of the gospel to a particular culture withour compromising the essence and particularities of the gospel.'
Timothy Keller, Center Church, p.89.
