The Holy Bible, Luke 21:12-19

12 But before all these, they shall lay their hands on you, and persecute you, delivering you up to the synagogues, and into prisons, being brought before kings and rulers for my name’s sake.

13 And it shall turn to you for a testimony.

14 Settle it therefore in your hearts, not to meditate before what ye shall answer:

15 For I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist.

16 And ye shall be betrayed both by parents, and brethren, and kinsfolks, and friends; and some of you shall they cause to be put to death.

17 And ye shall be hated of all men for my name’s sake.

18 But there shall not an hair of your head perish.

19 In your patience possess ye your souls.

The Holy Bible, Revelation 13:7

7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.

The Book of Mormon, 1 Nephi 14:13-14

13 And it came to pass that I beheld that the great mother of abominations did gather together multitudes upon the face of all the earth, among all the nations of the Gentiles, to fight against the Lamb of God.

14 And it came to pass that I, Nephi, beheld the power of the Lamb of God, that it descended upon the saints of the church of the Lamb, and upon the covenant people of the Lord, who were scattered upon all the face of the earth; and they were armed with righteousness and with the power of God in great glory.

The Book of Mormon, 1 Nephi 22:14

14 And every nation which shall war against thee, O house of Israel, shall be turned one against another, and they shall fall into the pit which they digged to ensnare the people of the Lord. And all that fight against Zion shall be destroyed, and that great whore, who hath perverted the right ways of the Lord, yea, that great and abominable church, shall tumble to the dust and great shall be the fall of it.

The Doctrine and Covenants, Section 88:94

94 And another angel shall sound his trump, saying: That great church, the mother of abominations, that made all nations drink of the wine of the wrath of her fornication, that persecuteth the saints of God, that shed their blood–she who sitteth upon many waters, and upon the islands of the sea–behold, she is the tares of the earth…

Conference Report, Ezra Taft Benson, October 1988

I testify that as the forces of evil increase under Lucifer’s leadership and as the forces of good increase under the leadership of Jesus Christ, there will be growing battles between the two until the final confrontation. As the issues become clearer and more obvious, all mankind will eventually be required to align themselves either for the kingdom of God or for the kingdom of the devil. As these conflicts rage, either secretly or openly, the righteous will be tested.

Journal of Discourses, Orson Pratt 7:29

When the time comes that the Saints of the Lamb of God are scattered upon all the face of the earth, among all nations and kingdoms of the Gentiles, and the multitudes gather against them to battles, we shall not find such unwise prayers answered. The Saints, instead of being all gathered out, will still be among the nations, for the power of the Lamb of God to descend upon the Saints of the Most High that are among all the nations and kingdoms of the Gentiles, and not only upon these, but also upon his covenant people, the descendants of Jacob; and they are to be armed with righteousness and the power of God in great glory. But gather them all out, and where have you got your Saints? It would completely falsify this saying.

Journal of Discourses, Orson Pratt 7:29

Where tyranny and oppression and all the horrors of despotism now reign, will be heard the Gospel of peace. Saints must be established in all those countries. Even in Russia, that place where they would almost put you to death if you brought a printed work of a religious nature into the empire–in that country, where they will not suffer you to propagate the Bible unmolested, whose religion is established by law, has the Gospel of Jesus Christ to be preached. Yes, the Church of the Saints is to be established there; and after it is established, there they are to gather together in multitudes, like other nations, to fight against it;
