'Lost' in the Bible

"Which one of you, if he has a hundred sheep and loses one of them, would not leave the ninety-nine in the open pasture and go look for the one that is lost until he finds it?

Returning home, he calls together his friends and neighbors, telling them, 'Rejoice with me, because I have found my sheep that was lost.'

Then when she has found it, she calls together her friends and neighbors, saying, 'Rejoice with me, for I have found the coin that I had lost.'

because this son of mine was dead, and is alive again -- he was lost and is found!' So they began to celebrate.

It was appropriate to celebrate and be glad, for your brother was dead, and is alive; he was lost and is found.'"

For the Son of Man came to seek and to save the lost."
