Luke 17:1-4 New International Version - UK (NIVUK)
Sin, faith, duty
17 Jesus said to his disciples: ‘Things that cause people to stumble are bound to come, but woe to anyone through whom they come. 2 It would be better for them to be thrown into the sea with a millstone tied round their neck than to cause one of these little ones to stumble. 3 So watch yourselves.
‘If your brother or sister[a] sins against you, rebuke them; and if they repent, forgive them. 4 Even if they sin against you seven times in a day and seven times come back to you saying “I repent,” you must forgive them.’
