"The canvasser who can speak clearly and distinctly about the merits of the book he wishes to sell, will find this a great help in his work. He may have an opportunity to read a chapter of the book, and by the music of his voice and the emphasis placed on the words, he can make the scene presented stand out as clearly before the mind of the listener as if it could actually be seen. GW 86.3"
"So then faith cometh by hearing, and hearing by the word of God."
Both passages connect effective communication with the reception of faith/understanding. EGW emphasizes clear and distinct speech to make the message vivid, while Romans 10:17 states that faith comes by hearing the word of God. The connection is thematic, focusing on the importance of hearing and understanding.
