“Have a Perfect Knowledge”
This verse has no reference to gaining a fulness of knowledge in and after the resurrection. We will not know all things at the time of our resurrection, but will come to know things as God knows them “in due time” (D&C 93:19). In the words of Joseph Smith, omniscience is not to be had immediately at death or even at the time of our rise from death. “It is not all to be comprehended in this world; it will be a great work to learn our salvation and exaltation even beyond the grave” (Teachings, p. 348).
