Some Children are Taken by God to Escape the Evils of the World

Joseph Smith

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 this earth. Therefore, if rightly considered, instead of mourning we have reason to rejoice as they are delivered from evil and we shall have them again. (Teachings of the Prophet Joseph Smith, 196)

Spencer W. Kimball

The only difference between the old and the 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 world. (Faith Precedes the Miracle, 104)
