In section 137, Joseph Smith has a vision of the celestial kingdom. Who was he surprised to see there?
His brother Alvin.
I saw my ... my brother Alvin, that has long since slept; And marveled how it was that he had obtained an inheritance in that kingdom, seeing that he had departed this life before the Lord had set his hand to gather Israel the second time, and had not been baptized. Doctrine & Covenants 137:5
