While speaking at the April Conference of the Church in Nauvoo in 1843, the Prophet Joseph Smith stated:
“It is not the design of the Almighty to come upon the earth and crush it and grind it to powder…There will be wars and rumours of wars, signs in the heavens above and on the earth beneath, the sun turned into darkness and the moon to blood, earthquakes in divers places,the seas heaving beyond their bounds; then will appear one grand sign of the Son of Man in heaven. But what will the world do? They will say it is a planet, a comet…”
(DHC 5:337)
