Goodspeed(i)
14 When they came to the people again, a man came up to him and fell on his knees, saying,
15 "Master, take pity on my son, for he has epilepsy, and is very wretched; he often falls into the fire or into the water.
16 And I brought him to your disciples and they have not been able to cure him."
17 Jesus answered, "O you unbelieving, obstinate people! How long must I be with you? How long must I put up with you? Bring him here to me!"
18 And Jesus reproved the demon and it came out of him, and from that moment the boy was cured.
19 Afterward, when he was alone, the disciples went to Jesus and said to him, "Why could we not drive it out?"
20 He said to them, "Because you have so little faith. For I tell you, if you have faith the size of a grain of mustard, you can say to this mountain, 'Move from here over to there!' and it will move, and nothing will be impossible for you."
