These kinds of questions are addressed in this noteworthy book by Lesslie Newbigin. A highly respected Christian leader and ecumenical figure, Newbigin provides a brilliant analysis of contemporary (secular, humanist, pluralist) culture and suggests how Christians can more confidently affirm their faith in such a context.
While drawing from scholars such as Michael Polanyi, Alasdair MacIntyre, Hendrikus Berkhof, Walter Wink, and Robert Wuthnow, The Gospel in a Pluralist Society is suited not only to an academic readership. This heartfelt work by a missionary pastor and preacher also offers to Christian leaders and laypeople some thoughtful, helpful, and provocative reflections.
