Forged during his struggle against Nazism, Bonhoeffer's striking notions of "religionless Christianity" (i.e., costly grace, direct religious engagement with political forces, and his own martyrdom) still speak directly to the situations faced by the Christians -- and Christianity -- of today. His key insights, combined with Floyd's meditations which address meaning and significance for today, are powerfully presented here in fifty key passages grouped into eight areas of Bonhoeffer's concern: church, world, discipleship, politics, love, Christ, creation, and the future.
