David O. McKay

“There are those in the world who say that jealousy, enmity, [and] 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” (Teachings of Presidents of the Church: David O. McKay, p. 23).
