For the Son of Man came to seek and to save the lost.
(Luke 19:10 -- ESV)

Amazing grace! How sweet the sound
That saved a wretch like me!
I once was lost, but now am found;
Was blind, but now I see.
(John Newton) 

When the rain falls
And it some days will
And the pavement under my feet
Sparkles silver in gold
In reflective light
That I otherwise wouldn't have seen

When the storm comes
And the strong wind blows
I will bow my head to push through
And every step that I take
I will watch and pray
And be sure my foothold is true

Jesus, don't you keep me from that storm
I want to walk that sacred ground
For You are Master of it all
And I am but a lost and found

And in the dry place
In the wilderness
When Your words seem so far away
I will think of my life and I will
Bless Your name
For Your promises never have failed

And when the night falls
At the end of days
I will lift my eyes to the Heavens
And we will shine like the stars
For eternal days
In Your presence forever and ever
(Robin Mark)

The Parable of the Lost Sheep
Now the tax collectors and sinners were all drawing near to hear him. ² And the Pharisees and the scribes grumbled, saying, “This man receives sinners and eats with them.”
³ So he told them this parable: ⁴ “What man of you, having a hundred sheep, if he has lost one of them, does not leave the ninety-nine in the open country, and go after the one that is lost, until he finds it? ⁵ And when he has found it, he lays it on his shoulders, rejoicing. ⁶ And when he comes home, he calls together his friends and his neighbors, saying to them, ‘Rejoice with me, for I have found my sheep that was lost.’ ⁷ Just so, I tell you, there will be more joy in heaven over one sinner who repents than over ninety-nine righteous persons who need no repentance.

The Parable of the Lost Coin

⁸ “Or 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? ⁹ And when she has found it, she calls together her friends and neighbors, saying, ‘Rejoice with me, for I have found the coin that I had lost.’ ¹⁰ Just so, I tell you, there is joy before the angels of God over one sinner who repents.”

The Parable of the Prodigal Son

¹¹ And he said, “There was a man who had two sons. ¹² And the younger of them said to his father, ‘Father, give me the share of property that is coming to me.’ And he divided his property between them. ¹³ Not many days later, the younger son gathered all he had and took a journey into a far country, and there he squandered his property in reckless living. ¹⁴ And when he had spent everything, a severe famine arose in that country, and he began to be in need. ¹⁵ So he went and hired himself out to one of the citizens of that country, who sent him into his fields to feed pigs. ¹⁶ And he was longing to be fed with the pods that the pigs ate, and no one gave him anything.
¹⁷ “But when he came to himself, he said, ‘How many of my father's hired servants have more than enough bread, but I perish here with hunger! ¹⁸ I will arise and go to my father, and I will say to him, “Father, I have sinned against heaven and before you. ¹⁹ I am no longer worthy to be called your son. Treat me as one of your hired servants.”’ ²⁰ And he arose and came to his father. But while he was still a long way off, his father saw him and felt compassion, and ran and embraced him and kissed him. ²¹ And the son said to him, ‘Father, I have sinned against heaven and before you. I am no longer worthy to be called your son.’²² But the father said to his servants, ‘Bring quickly the best robe, and put it on him, and put a ring on his hand, and shoes on his feet. ²³ And bring the fattened calf and kill it, and let us eat and celebrate. ²⁴ For this my son was dead, and is alive again; he was lost, and is found.’ And they began to celebrate.
