To impose Bible proclamation on the basis of authority or office, or using rhetorical devices to entice an audience place the focus on the speaker, not the message.
Preaching remembers that the only authority the speaker has, and the only reason it should be heard, is that it wholly shares the scriptures.
There is a possible life of great nobleness and usefulness for the preacher who, frankly recognising and cordial accepting the attitude towards his office which he finds on the world’s part, preaches truth and duty on their own intrinsic authority, and wins personal power and influence because he does not seek them, but seeks the prevalence of righteousness and the salvation of men’s souls.
