Nicodemus came to Jesus and said, “Rabbi, we know that you are a teacher who has come from God. For no one could perform the signs you are doing if God were not with him.” Jesus replied, “Very truly I tell you, no one can see the kingdom of God unless they are born again.... no one can enter the kingdom of God unless they are born of water and the Spirit. Flesh gives birth to flesh, but the Spirit gives birth to spirit.

We know what Christianity teaches about being 'Born Again'. I propose that a way to help comprehend this is to consider that you were already in a 'spirit form' before you were born here into your physical body. And your 'spirit' will remain connected to your body through your soul until it's time for the real you to leave (return home). Your awareness of there being a spiritual world influences how smoothly or not it is for your Spirit to travel back to the 'spirit world' (be born again to where you came from). Those who have accepted spiritual truths such as those that Christ brought have the faith to go return straight home. Those who have not learned the essence of the Eleventh Commandment (or else simply reject it) will have a much harder time traveling home again. But, once they finally allow their "guardian angels" (Forces of White Light) to guide them, they'll make it in good order / even if they have been wandering spirits {lost souls} for awhile.
