Why was Jesus rejected bythe people of his hometown?

Answer 1

The internal commentary found in the Gospels to explain this was a fulfillment of the ancient prophecy that a prophet of God is never welcome in the area in which he grew up.

The real-life, psychological explanation is that often among relatives and neighbours, with whom a religious leader was raised, the credibility of a teacher or preacher is suspect -- such as "we knew him when he was little..." or "S/he can't be THAT special!". This latter sentiment was part of the Gospel story: "But isn't He the son of that builder Yusef?"

The synoptic Gospels also outline an arc of Jesus' ministry; He started out, gained disciples, attracted many followers and listeners, reached a peak of popularity, then His innovative interpretations and miracles became less and less popular, until He was finally put to death for His amazing teachings. The anecdote of His lack of success in His home region can be placed in the latter part of that arc.

Answer 2

Jesus was rejected by the people of his hometown because they saw him as just a carpenter's son and couldn't accept his authority and wisdom. They were unwilling to see beyond his humble background and were offended by his teachings that challenged their beliefs and traditions. This rejection is a common experience for prophets and spiritual leaders throughout history.
