Matthew 17:19-21

New International Version

¹⁹ Then the disciples came to Jesus in private and asked, “Why couldn’t we drive it out?”

²⁰ He replied, “Because you have so little faith. Truly I tell you, if you have faith^(A) as small as a mustard seed,^(B) you can say to this mountain, ‘Move from here to there,’ and it will move.^(C) Nothing will be impossible for you.” ^[21] [a]
