Luke 15:8 – 10:  “What woman, having ten silver coins, if she loses one coin, does not light a lamp and sweep the house and seek diligently until she finds it?  And when she has found it, she calls together her friends and neighbors, saying, ‘Rejoice with me, for I have found the coin which I had lost.’ Just so, I tell you, there is joy before the angels of God over one sinner who repents.”
