I've received that assurance also. The reason it is not spelled out as such in His Word is that if it were, He would be obligated to "bring up" every mouse, fish, bird and insect that ever lived. This way He chooses some animals for eternal life, and others not.
Thank you for sharing your pain and your insight. Could you add me to the "Laz's Important Stuff" ping list? Thanks.
Of course.
