We don't know much about the first three decades of our Lord's life. Matthew and Luke offer their birth narratives. Luke refers to ritual circumcision and describes a prophetic encounter in the Jerusalem temple during Jesus' twelfth year. Other than that, we find our Lord's childhood, adolescence and young adulthood shrouded in shadows.
Speculation abounds, of course.
We see a boy who, like his father, becomes a carpenter. We assume relatively close family ties, a young man profoundly immersed in Torah. Yet, of none of this can we be certain. But near his thirtieth year Jesus of Nazareth goes public. He leaves his hometown, lays down his shop tools, bid's goodbye to his family.
