Why did the people of nazareth question Jesus' ability to teach in the synangogue?

The people of Nazareth questioned Jesus' ability to teach in the synagogue because they were familiar with him as the son of Joseph, a carpenter, and perceived him as an ordinary local figure rather than a learned teacher. Their skepticism stemmed from their disbelief that someone with his humble background could possess such wisdom and perform miracles. This lack of faith and recognition of his authority ultimately led to their rejection of him.
