Luke 15:12 (KJV)

I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance.

Either what woman having ten pieces of silver, if she lose one piece, doth not light a candle, and sweep the house, and seek diligently till she find it?

And when she hath found it, she calleth her friends and her neighbours together, saying, Rejoice with me; for I have found the piece which I had lost.

Likewise, I say unto you, there is joy in the presence of the angels of God over one sinner that repenteth.

And he said, A certain man had two sons:

And not many days after the younger son gathered all together, and took his journey into a far country, and there wasted his substance with riotous living.

And when he had spent all, there arose a mighty famine in that land; and he began to be in want.

And he went and joined himself to a citizen of that country; and he sent him into his fields to feed swine.

And he would fain have filled his belly with the husks that the swine did eat: and no man gave unto him.

And when he came to himself, he said, How many hired servants of my father's have bread enough and to spare, and I perish with hunger!
