Unbelief prevents miracles

MATTHEW

Matthew 13:55-59
55 And when he was come into his own country, he taught them in their synagogues, insomuch that they were astonished, and said, Whence hath this Jesus this wisdom and these mighty works?

56 Is not this the carpenter’s son? Is not his mother called Mary? And his brethren, James, and Joses, and Simon, and Judas? And his sisters, are they not all with us?

57 Whence then hath this man all these things? And they were offended at him.

58 But Jesus said unto them, A prophet is not without honor, save in his own country, and in his own house.

59 And he did not many mighty works there, because of their unbelief.

MARK

Mark 6:1-8
1 And he went out from thence, and came into his own country; and his disciples followed him.

2 And when the Sabbath day was come, he began to teach in the synagogue; and many hearing, were astonished at his words, saying, From whence hath this man these things?

3 And what wisdom is this that is given unto him, that even such mighty works are wrought by his hands?

4 Is not this the carpenter, the son of Mary, the brother of James and Joses, and of Judah and Simon?

5 And are not his sisters here with us? And they were offended at him.

6 But Jesus said unto them, A prophet is not without honor, save in his own country, and among his own kin, and in his own house.

7 And he could do no mighty work there, save that he laid his hands upon a few sick folk and they were healed.

8 And he marveled because of their unbelief. And he went round about the villages, teaching.
