"God as willed that we should seek and find His living Word in the witness of a brother, in the mouth of man. Therefore, the Christian needs another Christian who speaks God’s Word to him. He needs him again and again when he becomes uncertain and discouraged, for by himself he cannot help himself without belying the truth. He needs his brother man as a bearer and proclaimer of the divine word of salvation. He needs his brother solely because of Jesus Christ. The Christ in his own heart is weaker than the Christ in the word of his brother; his own heart is uncertain, his brother’s is sure.”
 Life Together, Dietrich Bonhoeffer, (Harper San Francisco, copyright Harper & Row 1954), page 23.
