And he said to them, “Why were you looking for me? Did you not know that I must be in my Father’s house?” But they did not understand what he said to them. He went down with them and came to Nazareth, and was obedient to them; and his mother kept all these things in her heart.Luke 2:49-51
Note: The word “house” is not in the Greek text. Luke 2:49 can also be translated, “Did you not know that I must be about my Father’s work/business (things of my Father)?”
Finding Jesus in the Father’s heart,
Mary kept him in her mother’s heart.
