Matthew 17:19-21

Worldwide English (New Testament)

¹⁹ Then the disciples came to Jesus alone. They asked him, `Why could we not drive the bad spirit out?'

²⁰ Jesus said to them, `Because you do not believe enough. I tell you the truth. If your strength to believe were as much as a little mustard seed, you could say to this hill, "Go, move over to that place!" And it would move. Nothing is too hard for you to do.

²¹ But this kind of bad spirit does not come out of a person unless people ask God and fast [do not eat food for a time].'
