And he said to his disciples, “Temptations to sin are sure to come; but woe to him by whom they come! It would be better for him if a millstone were hung round his neck and he were cast into the sea, than that he should cause one of these little ones to sin. Take heed to yourselves; if your brother sins, rebuke him, and if he repents, forgive him; and if he sins against you seven times in the day, and turns to you seven times, and says, ‘I repent,’ you must forgive him.”
–Luke 17:1-4
