More than head knowledge

Bonhoeffer was aware that the situation in which these young pastors would find themselves in the future would be one of great challenge, a test that could be met not by sheer intellectual book knowledge but only through a deep theological commitment that formed in them a rich spirituality. Bonhoeffer pushed them academically, bringing to bear the full weight of his academic credentials. But he did not do so outside of prayer, meditation, and confession. The student needed to encounter the living Christ as much as learn about him. Bonhoeffer would not settle for theology in his school but demanded a move into the theological, into concrete spiritual experiences of the living Christ.—Bonhoeffer as Youth Worker, pages 140-141

And that is one of the reasons I like Bonhoeffer so much. His theology is rooted and grounded in the practical.
