D&C 86

 As we study the Doctrine and Covenants, it becomes clear that the restoration of the gospel is still in its infancy, but growing a the blades are yet tender, thus - 

"Therefore your life and the priesthood have remained, and must needs remain through you and your lineage until the restoration of all things spoken by the mouths of all the holy prophets since the world began.

11 Therefore, blessed are ye if ye continue in my goodness, a light unto the Gentiles, and through this priesthood, a savior unto my people Israel..."  (Doctrine and Covenants 86:10–11)

Peter called it the restitution of all things.  In modern day, the Lord said restoration of all things.  In my mind, the restoration is still continuing.
