Sheeps and Goats.
If you don't know what this means then your a goat.
Read Matt 25:31-46
As for the Left Behind series it is totally fiction based on a literal reading of the book of Revelation. The current theology of a rapture with a second chance came about on the early 1800's. The actual theological view is that when Jesus returns it is immediately judgement day and your then segregated as a sheep or a goat.
Baa Baa!
Sorry dear, no Matt in the Tanakh...
"Baa Baa!"
Ummm...that describes the sound that both animals make.
