Matthew 17:20-21
Matthew 17:20-21 NASB1995
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.”]
