From Pikkert, Protestant Missionaries to the Middle East: Ambassadors of Christ or Culture?, pg. 268:
As this thesis has shown, the missionary community to the Middle East is too tainted by its own culture to presume to initiate change on social and political issues. Hence its primary task must be to present the person of Jesus Christ in all his winsomeness, even as it trusts the Spirit to draw people to the Saviour. It must then teach and disciple new believers in core Biblical truths, and draw them into a loving fellowship of believers, but will, once again, have to defer to the Spirit with respect to the nitty-gritty application of Christian truth to socio-political and cultural specifics. In other words, the local community of believers, responding to and wrestling with Biblical truths must, ultimately, be entrusted with the job of forging a church-centered New Testament spirituality applicable to their own culture. The missionary can, at best, guide at the level of basic Biblical principles.
