Luke 2:51

And he went down with them, and came to Nazareth; and he was subject unto them: and his mother kept all these sayings in her heart.

Here Luke virtually attributed to Mary the narratives just concluded, and without actually naming her as his source, nevertheless made that conclusion mandatory.

The precocious wisdom of the boy Jesus, and his certain consciousness of his unique relationship to the Father in heaven, were not looked upon by Jesus as sufficient to his earthly mission; but he recognized himself still to be a child. The hour of his emergence as the world's Saviour would be awaited by him until some sure indication of the Father's will informed him that "his hour" had come. In the meanwhile, he would not disgrace himself as a child prodigy. He manifested the noblest quality of youth, that of loving submission to his earthly parents.
