The sacredness of Far West, Missouri, is no doubt due to the understanding that the Prophet Joseph Smith conveyed to the brethren, at these early times, that Adam-ondi-Ahman, the place to which Adam and Eve fled when cast out of the Garden of Eden, is where Adam erected an altar unto God, and offered sacrifices, and that Far West was the spot where Cain killed Abel.
This, information, tends to explain why the Lord declared Far West to be a holy consecrated place; and no doubt explains why Satan claimed that place as his own, as it was here that he entered into a covenant with Cain, resulting in the death of Abel the first of mortal existence upon this earth.
