Matthew 17:19-20

Revised Standard Version Catholic Edition

¹⁹ Then the disciples came to Jesus privately and said, “Why could we not cast it out?” ²⁰ He said to them, “Because of your little faith. For truly, I say to you, if you have faith as a grain of mustard seed, you will say to this mountain, ‘Move from hence to yonder place,’ and it will move; and nothing will be impossible to you.”^[a]
