If there is no element of asceticism in our lives, if we give free rein to the desires of the flesh (taking care of course to keep within the limits of what seems permissible to the world), we shall find it hard to train for the service of Christ. When the flesh is satisfied it is hard to pray with cheerfulness or to devote oneself to a life of service which calls for much self-renunciation.

We must be ready to allow ourselves to be interrupted by God.....We must not.....assume that our schedule is our own to manage, but allow it to be arranged by God.

A god who let us prove his existence would be an idol.

Must the Christian go around looking for a cross to bear, seeking to suffer? No, insisted Bonhoeffer. Opportunities for bearing crosses will occur along life's way and all that is required is the willingness to act when the time comes. The needs of the neighbor, especially those of the weak and downtrodden, the victimized and the persecuted, the ill and the lonely, will become abundantly evident.

The church ... is not just to bandage the victims under the wheel, but to put a spoke in the wheel itself.

We must be ready to allow ourselves to be interrupted by God. God will be constantly crossing our paths and canceling our plans by sending us people with claims and petitions.

Innumerable times a whole Christian community has broken down because it had sprung from a wish dream… Every human wish dream that is injected into the Christian community is a hindrance to genuine community and must be banished if genuine community is to survive. He who loves his dream of a community more than the Christian community itself becomes a destroyer of the latter, even though his personal intentions may be ever so honest and earnest and sacrificial.
