God has put this Word into the mouth of others in order that it may be communicated to us. When one person is struck by the Word, he speaks it to others. God has willed that we should seek and find his living Word in the witness of a brother, in the mouth of a man. Therefore, the Christian needs another Christian who speaks God’s Word to him. He needs again and again when he becomes uncertain and discouraged, for by himself he cannot help himself without belying the truth.
He needs a brother 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.
