What does the phrase "My sheep will never perish" mean to you?

(John 10.28)

Does it make you lethargic in your salvation, or grateful in your security unto the point of bearing fruits?
Update: Apparently, none of the three atheists who have answered so far have ever read John 10. None of you have a right to claim you know more about the Bible than Christians again. Ever.
Update 2: @Ashley - What makes you think you're not? Christ's "sheep" are those whom he called to himself and who answered with faith in him.
