I have noticed increasingly that members feel a need to appeal to statistics and studies rather than to scriptures and plain spoken truth. I think the tools of the learned are a poor choice. They lack the power to convert that a pure statement of truth does. The more we can strike at the heart of a truth and lay it plain, the more the Holy Ghost can testify of its truth.
When a man speaks by the power of the Holy Ghost, he says things the Holy Ghost can testify of. He speaks of eternal truths. The scriptures say that
D&C 1:19 The weak things of the world shall come forth and break down the mighty and strong ones, that man should not counsel his fellow man, neither trust in the arm of flesh—
20 But that every man might speak in the name of God the Lord, even the Savior of the world;
This is not teachings of studies and statistics that is spoken of. In fact, it says that the weak things of the world shall come forth and break down the mighty and strong ones, that man should not counsel his fellow man, neither trust in the arm of flesh.
Counting on studies and statistics is trusting in the arm of flesh. It is based in man counseling his fellow man. It is the very sort of thing that God says he will break down, by using the weak things of the world.
Our power is the power of the Holy Ghost and the power of truth. We can be certain that when the Brother of Jared wrote things that were so powerful that they would overwhelm a man to read them, it was neither citing a recent study nor a bunch of statistics. But it resounded with the soul to the overpowering of the body when read by the power of God. We do not have any who writes like that in these days, nor have we known such in this dispensation. But of this we can be sure, we will not raise up another one like that man, none of us will ever become like him, by trying to teach and preach the gospel using the studies and statistics of the learned.
