That is counter-cultural to what my generation has heard for its whole existence. It’s Niebuhr’s classic idea of Christ transforming culture. And, if the church is to be “marketed” to the spiritual seekers under 40, this is our strongest “selling point”. The days of obligatory church attendance are over. If people fill our pews again it won’t be because we are offering something they can get anywhere else. It will be because we are sharing a Gospel that challenges and sustains them.
