If the passage of time is not really the same in Heaven and all moments there are currently “now,” this would mean: we don’t have to “wait” for our saved loved ones, because somehow they are already there, or will be there so quickly we wouldn’t experience their loss.
Which means the birth of Christ, the cross, the return, Adam and Eve, King David, the past, the future: all of it is happening for eternity.
Oh. My. What.
