Luke 17:2-6

It is better for him if a millstone is hung around his neck and he is thrown into the sea, than that he may cause one of these little ones to sin.

Be on your guard! If your brother sins, rebuke him; and if he repents, forgive him.

And if he sins against you seven times a day, and returns to you seven times, saying, ‘I repent,’ you shall forgive him.”

The apostles said to the Lord, “Increase our faith!”

But the Lord said, “If you had faith the size of a mustard seed, you could say to this mulberry tree, ‘Be uprooted and be planted in the sea’; and it would obey you.
