By sheer grace, God will not permit us to live even for a brief period in a dream world. He does not abandon us to those rapturous experiences and lofty moods that come over us like a dream. God is not a God of the emotions but of the truth. Only that fellowship which faces such disillusionment, with all its unhappy and ugly aspects, begins to be what it should be in God’s sight, begins to grasp in faith the promise that is given to it. The sooner the shock of this disillusionment comes to an individual and to a community the better for both. A community which cannot bear and cannot survive such a crisis, which insists upon keeping its illusion when it should be shattered, permanently loses in that moment the promise of Christian community. Sooner or later it will collapse. 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.
The very wise words of Bonhoeffer in Life Together page 27. I am pondering them yet again.
