Matthew 17:7, 20-21

And Jesus came to them and touched them and said, “Get up, and do not be afraid.”

And He *said to them, “Because of the littleness of your faith; for truly I say to you, if you have faith the size of a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible to you. [But this kind does not go out except by prayer and fasting.”]
