OP, some musings and questions if you ever do come back.

Will everyone die or will some still be left on this Earth to achieve a purpose?

God has told me that there is a time of darkness ahead, one borne out of Greed of men that have more Faith in money than they do their fellow man or God, does this sound similar to your experience?

Have you given thought that the children you saw in Heaven may or may not have been children, but were merely in the spiritual form of Children?
