Time is an earthly, mortal concept. We live our lives in a linear path, from birth to death in a long trudge forward. No going back to live parts of it again (except as memories), mo skipping ahead to see what happens - just one day at a time, until it ends.
So, consider this: When we finish our time here on Earth, I believe we're no longer held to that linear time constraint. All of what has gone before, and is yet to come, is at our etherial fingertips. Want to watch Mark Twain have breakfast? How about look in on your great-grandchild's wedding? The love of your life - what were they like as a child? It's waiting for you.
Now, when you feel like you've known someone all your life, maybe you have - or maybe they will. And thinking that someone who loves me has been there all along, is pretty nice.
