‘Supposing one of you has a hundred sheep,’ he said, ‘and you lose one of them. What will you do? Why, you’ll leave the ninety-nine out in the countryside, and you’ll go off looking for the lost one until you find it! And when you find it, you’ll be so happy – you’ll put it on your shoulders and come home, and you’ll call your friends and neighbours in. “Come and have a party!” you’ll say. “Celebrate with me! I’ve found my lost sheep!”
‘Well, let me tell you: that’s how glad they will be in heaven over one sinner who repents – more than over ninety-nine righteous people who don’t need repentance.
Luke 15:4-7, New Testament for Everyone
