When you get into the active operation of your proselyting program, this is a concept you absolutely must have. It has been our traditional course in days past, unfortunately all too frequently, to say, 'Here is the Bible, and the Bible says this and this, and therefore the Gospel has been restored.' Well now, there is no person on earth that believes the Bible more than I do. I read it and ponder its words. I know that what is in it is true. But let me tell you, it is not the Bible that brings people into the Church; it is the Book of Mormon and latter-day revelation. We can use the Bible to lay a foundation, and to point people's attention to Joseph Smith and the Book of Mormon, but until we get involved with latter-day revelation, the process of conversion does not begin to operate in any substantial degree in the heart of an investigator. The Lord said to Joseph Smith: 'this generation shall have my word through you...' (D&C 5:10). That is his decree. They either get it through Joseph Smith or they do not get it, and our whole perspective is: Joseph Smith and the Book of Mormon, the Book of Mormon and Joseph Smith.
