Christian author Christian Author and apologist Ravi Zacharias …who I have come to be an avid listener to of late… tells us that the reason that we are forever surprised by the passage of time… Looking in the mirror and recognizing that the grey bearded gink in that mirror really is you … How fast kids are growing up, our friends growing older and so on…is because we aren’t meant to be living in a finite environment. We’re supposed to be living in eternity.
