When one contemplates eternity, it brings a sense of something that is timeless, without beginning or ending-something that has always been and will always be. Let's step forward in concept and realize that all-you, me, and everyone-exist in and as a part of Eternity. In this earthly plane we exist in time and we are part of humanness, but in Absolute Reality, we are existent within and as a part of Eternity.
Now Eternity and all that it is, has always existed and thus has had sufficient endless time to become conscious of itself. All timed existences, inclusive of humanity, are as thought processes moving within Eternity. Eternity or Eternal Life is another way of describing the Ultimate Life Consciousness of all that is, or-God.
