The Parable of the Lost Coin

Luke 15:1-2, 8-10

Now the tax collectors and sinners were all gathering around to hear Jesus. But the Pharisees and the teachers of the law muttered, “This man welcomes sinners and eats with them.”...
....suppose a woman has ten silver coins[a] and loses one. Doesn’t she light a lamp, sweep the house and search carefully until she finds it? And when she finds it, she calls her friends and neighbors together and says, ‘Rejoice with me; I have found my lost coin.’ In the same way, I tell you, there is rejoicing in the presence of the angels of God over one sinner who repents.”

God wants to find sinners, he is looking for them! No matter what our sin, he wants us with him! If we are "friends of God" we should be happy each time a sinner turns to God. We should Party!
