again, age, course, end, eternal, forever, permanent, time, world, worlds

age; world order; eternity (ap aion or pro aion, from the beginning; eis aion, and the strengthened form eis tous aion, ton aion, always, forever); Aeon (personified as an evil force); existence, the present life (Mt 13:22; Mk 4.19)

In Plato the term [aion] is developed so as to represent a timeless, immeasurable and transcendent super-time, an idea of time in itself. Plutarch and other earlier Stoics appropriate this understanding, and from it the Mysteries of Aion, the god of eternity, could be celebrated in Alexandria, and gnosticism could undertake its own speculations on time.

In Hellenistic philosophy the concept of aeons contributed towards a solution of the problem of the world-order. The aeons were assumed to be mediating powers which bridge the infinite qualitative distinction between God and the world. They are an emanation of the divine pleroma, the fullness of the divine Being….

The statements of the Johannine [John, 1 John, 2 John, 3 John] writings, which cannot always be pinned down with absolute certainty of meaning.., Heb., where the meaning is quite clear .. and naturally those cases where aion is used in the plural, all reveal a strong inclination to conceive of a timeless, because post-temporal, eternity… As in the OT [Old Testament], these statements reveal the background conviction that God's life never ends, i.e. that everything belonging to him can also never come to an end…

S&H 335:7 - Spirit, God, has created all in and of Himself. Spirit never created matter. There is nothing in Spirit out of which matter could be made, for, as the Bible declares, without the Logos, the Aeon or Word of God, "was not anything made that was made." Spirit is the only substance, the invisible and indivisible infinite God. Things spiritual and eternal are substantial. Things material and temporal are insubstantial.
