(7:25) Quote from President Benson about the Times of the Gentiles
"The Lord has designated these days in which we live as the 'times of the Gentiles.' The Gentile nations are the so-called Christian nations—North and South America and the European nations from which we came. The 'times of the Gentiles' refers to that period of time extending from when the gospel was restored to the world (1830) to when the gospel will again be preached to the Jews—after the Gentiles have rejected it...
"The rejection of the testimony of the servants of God by the nations of the world will bring the consequence of greater calamities..."

(16:53) Sign: Stars fall from heaven
"November 13. About 4 o’clock a.m. I was awakened by Brother Davis knocking at my door, and calling me to arise and behold the signs in the heavens. I arose, and to my great joy, beheld the stars fall from heaven like a shower of hail stones; a literal fulfillment of the word of God as recorded in the holy scriptures as a sure sign that the coming of Christ is close at hand. In the midst of this shower of fire, I was led to exclaim, how marvelous are thy works O Lord! I thank thee for thy mercy unto thy servant, save me in thy kingdom for Christ’s sake: Amen."

(31:06) Scripture that says wrath is not for the righteous
16 For the time soon cometh that the fulness of the wrath of God shall be poured out upon all the children of men; for he will not suffer that the wicked shall destroy the righteous.
17 Wherefore, he will preserve the righteous by his power, even if it so be that the fulness of his wrath must come, and the righteous be preserved, even unto the destruction of their enemies by fire. Wherefore, the righteous need not fear; for thus saith the prophet, they shall be saved, even if it so be as by fire.
18 Behold, my brethren, I say unto you, that these things must shortly come; yea, even blood, and fire, and vapor of smoke must come; and it must needs be upon the face of this earth; and it cometh unto men according to the flesh if it so be that they will harden their hearts against the Holy One of Israel.

3 Saying, Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads.
4 And I heard the number of them which were sealed: and there were sealed an hundred and forty and four thousand of all the tribes of the children of Israel.
