Moroni has certainly asked to know the future of this record, and, just as surely, it was revealed to him. Much of the liturgical nature of the book of Moroni could be explained as Moroni’s instructions to Joseph on how to establish the Church that would be founded on this book. At this point, he notes that the one to bring it forth will be blessed.
As the last one having responsibility for the record, and being the one who was to bury it, it is understandable that Moroni would be very curious about who would take it “out of the earth” and bring it to light.
