Many of the signs are terrifying and dreadful. The prophets have warned that the earth will experience great turmoil, wickedness, war, and suffering. The prophet Daniel said that the time before the Second Coming would be a time of trouble such as the earth has never known (see Daniel 12:1). The Lord said, “The love of men shall wax cold, and iniquity shall abound” (D&C 45:27). “And all things shall be in commotion; and … fear shall come upon all people” (D&C 88:91). We can expect earthquakes, disease, famines, great storms, lightnings, and thunder (see Matthew 24:7; D&C 88:90). Hailstorms will destroy the crops of the earth (see D&C 29:16).
Jesus told His disciples that war would fill the earth: “Ye shall hear of wars and rumours of wars. . . . For nation shall rise against nation, and kingdom against kingdom” (Matthew 24:6-7). The Prophet Joseph Smith said: “Be not discouraged when we tell you of perilous times, for they must shortly come, for the sword, famine, and pestilence are approaching. There shall be great destructions upon the face of this land, for ye need not suppose that one jot or tittle of the prophecies of all the holy prophets shall fail, and there are many that remain to be fulfilled yet”
