our verbosity is a cover for insincerity or uncertainty

In that premortal council, when Jesus meekly volunteered, saying, “Here am I, send me,” it was one of those significant moments when a few words are preferred to many. Never has one individual offered, in so few words. To do so much for so many as did Jesus when he meekly proffered Himself as ransom for all of us, billions and billions of us!

By contrast, in our unnecessary multiplication of words, there is not only a lack of clarity but often an abundance of vanity. Sometimes, too, our verbosity is a cover for insincerity or uncertainty. If there could be more subtraction of self, there would be less multiplication of words.
