Fruitful ministry in the century must embrace the unavoidable reality of the city.  A Center Church theological vision affirms that center cities are wonderful, strategic, and underserved places for gospel ministry and recognizes that virtually all ministry contexts are increasingly shared by urban and global forces. Regardless of your particular cultural or geographical context, you will need to consider the city when forming a theological vision that engages the people you are trying to reach.  This eBook contains the fifth part of Center Church, “Cultural Engagement.” In it, Keller discusses four models for engaging urban culture, acknowledging that each model has strengths and weaknesses—ways in which it reflects a particular biblical emphasis and other ways in which it reflects an unbiblical imbalance or idol. The Center church model for cultural engagement blends the key insights of each model in a way that we believe is more biblically faithful and also fruitful for reaching urban culture.
