Welcome to the prodigal sheep
Which one of you with a hundred sheep, if he lost one, would fail to leave the ninety-nine in the desert and go after the missing one till he found it?' - Luke 15:4 (New Jerusalem Bible)
'But the father said to his servants, "Quick! Bring out the best robe and put it on him; put a ring on his finger and sandals on his feet. Bring the calf we have been fattening, and kill it; we will celebrate by having a feast, because this son of mine was dead and has come back to life; he was lost and is found."' - Luke 15:22-24 (New Jerusalem Bible)
