Dietrich Bonhoeffer on Discipline

We claim liberty from all legal compulsion... and play this off against the proper evangelical use of discipline and asceticism; we thus excuse our self-indulgence and irregularity in prayer, in meditation, and in our bodily life. But the contrast between our behaviour and the word of Jesus is all too painfully evident. We forget that discipleship means estrangement from the world, and we forget the real joy and freedom which are the outcome of a devout rule of life.
COD p189

Dietrich Bonhoeffer on Discipleship

Christianity without the living Christ is inevitably Christianity without discipleship, and Christianity without disipleship is always Christianity without Christ.
