Luke 17:4-6

4Even if they sin against you seven times in a day and seven times come back to you saying ‘I repent,’ you must forgive them.”

5The apostles said to the Lord, “Increase our faith!”

6He replied, “If you have faith as small as a mustard seed, you can say to this mulberry tree, ‘Be uprooted and planted in the sea,’ and it will obey you.
