"While much must be taken on faith alone, there is individual revelation through which we may know the truth. 'There is a spirit in man, and the inspiration of the almighty giveth them understanding' (Job 32:8). What may be obscure in the scriptures can be made plain through the Gift of the Holy Ghost. We can have as full an understanding of spiritual things as we are willing to earn."
