“All Children Who Die Before They Arrive at the Years of Accountability Are Saved in the Celestial Kingdom”
Doctrine and Covenants 137:10
10 And I also beheld that all children who die before they arrive at the years of accountability are saved in the celestial kingdom of heaven.
President Joseph Fielding Smith said:
“Children who die in childhood will not be deprived of any blessing. When they grow, after the resurrection, to the full maturity of the spirit, they will be entitled to all the blessings which they would have been entitled to had they been privileged to tarry here and receive them.”
