In Luke 15, the parable of the lost coin emphasizes the doctrine of redemption. Redemption is all about what God was willing to pay for us and this parable emphasized that a lost person has value.
8 "Or what woman, if she has ten silver coins and loses one coin, does not light a lamp and sweep the house and search carefully until she finds it?
9 "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!'
10 "In the same way, I tell you, there is joy in the presence of the angels of God over one sinner who repents."
The joy of the woman in the parable was matched by God's joy in heaven over one sinner who has repented. Redemption is one of the three major works of the cross. Propitiation, reconciliation, and redemption are those works. Redemption emphasizes what God the Father paid for us. We are worth a Son to him as First Peter 1:18-19 states: we are not redeemed with silver or gold but with the precious blood of the lamb of God. That is the value God has placed on you.
