Parable of the Lost Sheep

I'm using these verses for I'm giving at a upcoming retreat.  I'm posting them so I can print them out at work tomorrow.  

Feel free to read and ponder these verses.

Can you point to times when you were lost, but then found?

Psalm 23 ; 4-5  
Even though I walk
    through the darkest valley,[a]
I will fear no evil,
    for you are with me; 
Your rod and your staff comfort me.

Luke 15:1-7New International Version (NIV)
The Parable of the Lost Sheep
Now the tax collectors and sinners were all gathering around to hear Jesus. 2 But the Pharisees and the teachers of the law muttered, “This man welcomes sinners and eats with them.”
3 Then Jesus told them this parable: 4 “Suppose one of you has a hundred sheep and loses one of them. Doesn’t he leave the ninety-nine in the open country and go after the lost sheep until he finds it? 5 And when he finds it, he joyfully puts it on his shoulders 6 and goes home. Then he calls his friends and neighbors together and says, ‘Rejoice with me; I have found my lost sheep.’
7 I tell you that in the same way there will be more rejoicing in heaven over one sinner who repents than over ninety-nine righteous persons who do not need to repent.
VS. 14-15
14 “I am the good shepherd; I know my sheep and my sheep know me— 15 just as the Father knows me and I know the Father—and I lay down my life for the sheep. 16 I have other sheep that are not of this sheep pen. I must bring them also. They too will listen to my voice, and there shall be one flock and  one Shepard.
