What do you think?  If a man owns a hundred sheep, and one of them wanders away, will he not leave the ninety-nine on the hills and go to look for the one that wandered off?  And if he finds it, truly I tell you, he is happier about that one sheep than about the ninety-nine that did not wander off.  In the same way your Father in heaven is not willing that any of these little ones should perish.

(Matthew 18:12-14 -- NIV)
