The idea that we came from heaven to this earth is instinctively felt and cherished by many in Christianity though their clergy officially revile it.
The pre-Earth existence -- not reincarnation but simply the idea that we once lived as spirits with God our Father and now live here, clothed in mortal flesh -- is one of the beautiful doctrines explained in the restoration of the Gospel.
While reading in 1st John the other day, I came across this exquisite verse:
"I write unto you, little children, because ye have known the Father."
If we did not once live, as conscious, sentient beings, with our Heavenly Father, what could this verse possibly mean?
