Matthew 18:12-15

‘What do you think? If a man owns a hundred sheep, and one of them wanders away, will he not leave the ninety-nine on the hills and go to look for the one that wandered off? And if he finds it, truly I tell you, he is happier about that one sheep than about the ninety-nine that did not wander off. In the same way your Father in heaven is not willing that any of these little ones should perish. ‘If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over.
