By sheer grace, God will not permit us to live even for a brief period in a dream world…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 this shock of disillusionment comes to an individual and to a community the better for both…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.
God hates visionary dreaming; it makes the dreamer proud and pretentious. The man who fashions a visionary ideal of community demands that it be realized by God, by others, and by himself. He enters the community of Christians with his demands, sets up his own law, and judges the brethren and God Himself accordingly.
…because God has bound us together in one body with other Christians in Jesus Christ…we enter into that common life not as demanders but as thankful recipients. We thank God for what He has done for us. We thank God for giving us brethren who live by His call, by His forgiveness, and His promise.
…Even when sin and misunderstanding burden the communal life, is not the sinning brother still a brother, with whom I, too, stand under the Word of Christ? Will not his sin be a constant occasion for me to give thanks that both of us may live in the forgiving love of God in Jesus Christ? Thus the very hour of disillusionment with my brother becomes incomparably salutary, because it is so thoroughly teaches me that neither of us can ever live by our own words and deed, but only by that one Word and Deed which really binds us together-the forgiveness of sins in Jesus Christ. When the morning mists of dreams vanish, then dawns the bright day of Christian fellowship.
