Daniel 2:44
"And in the days of these kings shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever."
David O. McKay

"There are those in the world who say that jealousy, enmity, selfishness in men's hearts will always preclude the establishing of the ideal society known as the kingdom of God. No matter what doubters and scoffers say, the mission of the Church of Jesus Christ is to eliminate sin and wickedness from the hearts of men, and so to transform society that peace and good will will prevail on this earth." (Gospel Ideals, p. 10)
