God hates visionary dreaming; it makes the dreamer proud and pretentious.
Whoops. No commentary needed. Read on...
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 demands, sets up his own laws and judges the brethren and God accordingly. He stands adamant, a living reproach to all others in the circle of brethren. He acts as if he is the creator of the Christian community, as if his dream binds people together. When things do not go his way, he calls the effort a failure. When his ideal picture is destroyed, he sees the community going to pot. So he becomes first an accuser of the brethren, then an accuser of God, and finally the despairing accuser of himself.
Because God has already laid the only foundation of our fellowship, because God has bound us together in one body with other Christians in Jesus Christ, long before we entered into the common life with them, 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. We do not complain of what God does not give us; we rather thank God for what he does give us daily. And is what has been given us not enough: brothers, who will go on living with us through sin and need under the blessing of his grace? Is the divine gift of Christian fellowship anything less than this, any day, even the most difficult and distressing day? 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 so thoroughly teaches me that neither of us can ever live by our own words and deeds, but only by the one Word and Deed which really binds us together -- the forgiveness of sins in Christ Jesus. When the morning mists of dreams vanish, then dawns the bright day of Christian fellowship.
