We are participants in this continuum, and so to that extent we say that we are "in" time. But many have direct experiences of timelessness. So paradoxically, humans directly experience both time and timelessness. As T. S. Eliot said, human life is lived at the intersection of time and timelessness (eternity). That is the specific form of our humanity.
Thank you so much for your amazingly informative and thought-provoking essay/post, Alamo-Girl!
And I'd venture to say that many Christians are like me - more aware of being alive in timelessness than being alive in time.
