I am intrigued by Brueggemann's move to not treat this as a general text meant for all Christians. Rather, Brueggemann focuses more intently on the particularity of Paul. Brueggemann writes:
My attention is drawn, however, not only to the change in Paul but also to the change in faith enacted by the spirit through Paul. Indeed the church is always running, even yet, to catch up with Paul in his radical, daring newness in the gospel. A sermon focus might be, not on the psychology of transformation and vocation, but on Paul’s transformed articulation of the gospel.Brueggemann pushes me I think in the right direction.
