Matthew 18:12-15

“What do you think? If any man has a hundred sheep, and one of them has gone astray, does he not leave the ninety-nine on the mountains and go and search for the one that is straying? If it turns out that he finds it, truly I say to you, he rejoices over it more than over the ninety-nine which have not gone astray. So it is not the will of your Father who is in heaven that one of these little ones perish. “If your brother sins, go and show him his fault in private; if he listens to you, you have won your brother.
