And it came to pass, that when Jesus had finished these parables, He departed thence.  And when He was come into His own country, He taught them in their synagogue, insomuch that they were astonished, and said, “Whence hath this Man this wisdom, and these mighty works?  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? Whence then hath this man all these things?”  And they were offended in Him. But Jesus said unto them,
“A prophet is not without honour, save in his own country, and in his own house.”
And He did not many mighty works there because of their unbelief.
Matthew 13:53-58

For more on this event in the life of Jesus you might want to read the  account according to the Gospel of Luke the physician and Historian (Luke 4:16-30).

At this point in the ministry of Jesus His home town where He grew up rejected Him as being the Messiah, due to their unbelief.  I have a thought that Jesus is offended by the unbelief of His home town people,  however He does not let that stop His word or works.

The reason for many of our failures to receive answer to prayers is due to our rejection of the Lord’s ministry, and  that is due to our unbelief. Because of that He does not do many  mighty works.

Lord Jesus I pray that You help my faith, and increase my faith, so that Your mighty works might continue in me.  Amen.
