Zion will be a place of physical and spiritual refuge to the pure in heart.
’For thus shall my church be called in the last days, even The Church of Jesus Christ of Latter-day Saints.
Verily I say unto you all: Arise and shine forth, that thy light may be a standard for the nations;
And that the gathering together upon the land of Zion, and upon her stakes, may be for a defense, and for a refuge from the storm, and from wrath when it shall be poured out without mixture upon the whole earth.’ (DC 115:4-6)
’And it shall be called the New Jerusalem, a land of peace, a city of refuge, a place of safety for the saints of the Most High God;
And the glory of the Lord shall be there, and the terror of the Lord also shall be there, insomuch that the wicked will not come unto it, and it shall be called Zion.’ (DC 45:66-7)
Joseph Smith
"…The time is soon coming, when no man will have any peace but in Zion and her stakes.
“I saw men hunting the lives of their own sons, and brother murdering brother, women killing their own daughters, and daughters seeking the lives of their mothers. I saw armies arrayed against armies. I saw blood, desolation, fires. The Son of man has said that the mother shall be against the daughters, and the daughter against the mother. These things are at our doors. They will follow the Saints of God from city to city. Satan will rage, and the spirit of the devil is now enraged. I know not how soon these things will take place.” (Teachings of the Prophet Joseph Smith, p. 161 as taken from Latter-day Commentary on the Book of Mormon compiled by K. Douglas Bassett, p. 134)
