Eternity is a mysterious absence of times and ages: an endless length of ages always present, and for ever perfect. For as there is an immovable space wherein all finite spaces are enclosed, and all motions carried on and performed; so is there an immovable duration, that contains and measures all moving durations. Without which first the last could not be; no more than finite places, and bodies moving without infinite space. All ages being but successions correspondent to those parts of the Eternity wherein they abide, and filling no more of it, than ages can do. Whether they are commensurate with it or no, is difficult to determine. But the infinite immovable duration is Eternity, the place and duration of all things, even of infinite space itself: the cause and end, the author and beautifier, the life and perfection of all.
Eternity magnifies our joys exceedingly, for whereas things in themselves began, and quickly end; before they came, were never in being; do service but for few moments; and after they are gone pass away and leave us for ever, Eternity retains the moments of their beginning and ending within itself: and from everlasting to everlasting those things were in their times and places before God, and in all their circumstances eternally will be, serving Him in those moments wherein they existed, to those intents and purposes for which they were created.
Thomas Traherne, Fifth Century, 7 & 8
