1. by a great faith:
5 When Jesus had entered Capernaum, a centurion came to him, asking for help.6 “Lord,” he said, “my servant lies at home paralyzed and in terrible suffering.”7 Jesus said to him,“I will go and heal him.”8 The centurion replied,“Lord, I do not deserve to have you come under my roof. But just say the word, and my servant will be healed. 9 For I myself am a man under authority, with soldiers under me. I tell this one, ‘Go,’ and he goes; and that one, ‘Come,’ and he comes. I say to my servant, ‘Do this,’ and he does it.”10 When Jesus heard this, he was astonished and said to those following him,“I tell you the truth, I have not found anyone in Israel with such great faith.11 I say to you that many will come from the east and the west, and will take their places at the feast with Abraham, Isaac and Jacob in the kingdom of heaven. 12 But the subjects of the kingdom will be thrown outside, into the darkness, where there will be weeping and gnashing of teeth.”13 Then Jesus said to the centurion,“Go! It will be done just as you believed it would.” And his servant was healed at that very hour. (Mt 8:5-13, NIV, emphasis mine).
2. by the lack of faith:
Jesus left there and went to his hometown, accompanied by his disciples. 2 When the Sabbath came, he began to teach in the synagogue, and many who heard him were amazed.“Where did this man get these things?” they asked.“What’s this wisdom that has been given him, that he even does miracles! 3 Isn’t this the carpenter? Isn’t this Mary’s son and the brother of James, Joseph, Judas and Simon? Aren’t his sisters here with us?”And they took offense at him.4 Jesus said to them,“Only in his hometown, among his relatives and in his own house is a prophet without honor.”
