When the disciples were alone with Jesus, they asked him, ‘Why could we not make the bad spirit leave the boy?’ Jesus replied, ‘You could not do it because you do not trust God very much. I tell you this. You may believe in God only a little bit, like a very small seed. Even then, you could say to this mountain, “Go away from this place and move to that other place.” Then it will move. Nothing will be impossible for you to do.’ [ Matthew 17:19-20
門徒暗暗地到耶穌跟前，說：「我們為甚麼不能趕出那鬼呢？」 耶穌說：「是因你們的信心小。我實在告訴你們，你們若有信心，像一粒芥菜種，就是對這座山說：『你從這邊挪到那邊』，它也必挪去；並且你們沒有一件不能做的事了。 馬太福音 17:19-20
