The Disciples’ Failure to Heal

17:14 When24 they came to the crowd, a man came to him, knelt before him, 17:15 and said, “Lord, have mercy on my son, because he has seizures25 and suffers terribly, for he often falls into the fire and into the water. 17:16 I brought him to your disciples, but26 they were not able to heal him.” 17:17 Jesus answered,27 “You28 unbelieving29 and perverse generation! How much longer30 must I be with you? How much longer must I endure31 you?32 Bring him here to me.” 17:18 Then33 Jesus rebuked34 the demon and it came out of him, and the boy was healed from that moment. 17:19 Then the disciples came35 to Jesus privately and said, “Why couldn’t we cast it out?” 17:20 He told them, “It was because of your little faith. I tell you the truth,36 if you have faith the size of37 a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; nothing38 will be impossible for you.”39
