Just as surely as God desires to lead us to a knowledge of genuine Christian fellowship, so surely must we be overwhelmed by a great disillusionment with others, with Christians in general, and, if we are fortunate, with ourselves.

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 the God of 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.
