Parable of the Lost Coin: God’s love for those who don’t know they are lost; diligence in seeking the lost
Or what woman, if she had ten drachma coins, if she lost one drachma coin, wouldn’t light a lamp, sweep the house, and seek diligently until she found it? When she has found it, she calls together her friends and neighbors, saying, ‘Rejoice with me, for I have found the drachma which I had lost.’ Even so, I tell you, there is joy in the presence of the angels of God over one sinner repenting.
