…To reach people we must appreciate and adapt to their culture, but we must also challenge and confront it. This is based on the biblical teaching that all cultures have God’s grace and natural revelation in them, yet they are also in rebellious idolatry. If we overadapt to a culture, we have accepted the culture’s idols. If, however, we underadapt to a culture, we may have turned our own culture into an idol, an absolute. If we overadapt to a culture, we aren’t able to change people because we are not calling them to change. If we underadapt to a culture, no one will be changed because no one will listen to us; we will be confusing, offensive, or simply unpersuasive. To the degree a ministry is overadapted or underadapted to a culture; it loses life-changing power.
