"Who can hear it?"

1. John 6: 60
   60 Many therefore of his disciples, when they had heard this, said, This is an hard saying; who can hear it?
2. D&C 128: 9
   9 It may seem to some to be a very bold doctrine that we talk of—a power which records or binds on earth and binds in heaven. Nevertheless, in all ages of the world, whenever the Lord has given a dispensation of the priesthood to any man by actual revelation, or any set of men, this power has always been given. Hence, whatsoever those men did in authority, in the name of the Lord, and did it truly and faithfully, and kept a proper and faithful record of the same, it became a law on earth and in heaven, and could not be annulled, according to the decrees of the great Jehovah. This is a faithful saying. Who can hear it?
