The Incorrect Doctrine of Innocent Children Going to Hell — Corrected by Joseph Smith

“Truly it is one of the sweetest and most soul-satisfying doctrines of the gospel! It is also one of the great evidences of the divine mission of the Prophet Joseph Smith. In his day the fiery evangelists of Christendom were thundering from their pulpits that the road to hell is paved with the skulls of infants not a span long because careless parents had neglected to have their offspring baptized. Joseph Smith’s statements, as recorded in the Book of Mormon and latter-day revelation, came as a refreshing breeze of pure truth: little children shall be saved. Thanks be to God for the revelations of his mind where these innocent and pure souls are concerned!”

Joseph Smith’s Thoughts on the Death of Little Children

“In my leisure moments I have meditated upon the subject, and asked the question, why it is that infants, innocent children, are taken away from us, especially those that seem to be the most intelligent and interesting. . . . The Lord takes many away even in infancy, that they may escape the envy of man, and the sorrows and evils of this present world; they were too pure, too lovely, to live on earth; therefore, if rightly considered, instead of mourning we have reason to rejoice as they are delivered from evil, and we shall soon have them again. . . .  All children are redeemed by the blood of Jesus Christ, and the moment that children leave this world, they are taken to the bosom of Abraham.  The only difference between the old and young dying is, one lives longer in heaven and eternal light and glory than the other, and is freed a little sooner from this miserable wicked world.”
Joseph Smith, Teachings, p. 196-197
