In response
to the question, "How long is eternity?" we read the following from
the Millennial Star in 1943:
Endless: continuing forever . . . and ever.
Billions of years, repeating themselves without ceasing. Indefinite, but vast
and immeasurable period of time--aeons Consider these references: "There
is a God in Heaven who is infinite and eternal, from everlasting to
everlasting, the same unchangeable God, the former of Heaven and earth and all
things which are in them" (D. & C. 20:17), or prayer of Moses in Psalm
90: "Before the mountains were brought forth or even thou hadst formed the
earth and the world from everlasting to everlasting Thou art God." (“Do
You Know—Answers,” Millennial Star 105, no. 13 [April 1943]: 255)
