It's a concept many of us think of. In my life, I have met people I never had any reason to know or meet, that I know from the first time I laid eyes on them.

In my faith, life can be eternal. We have a pre-existence, which could explain the above comment. We did know other spirits there. Why wouldn't we recognize them other than there being a veil that causes us to forget for awhile...? And we will know them in the next 'classroom', I know for sure.

I don't think when we die, that we come back as bugs or cows or plants. But a loving Deity could choose to give us a second chance to learn what we're supposed to, couldn't He?

Did you ever hear or read of Bridey Murphy? Google her story. It rather does make questions for me.
