Everyone who heard him was amazed at his understanding and his answers. [He was twelve years old]. When his parents saw him, they were astonished. His mother said to him, "Son, why have you treated us like this? Your father and I have been anxiously searching for you." "Why were you searching for me?" he asked. "Didn't you know I had to be in my Father's house?" But they did not understand what he was saying to them. Then he went down to Nazareth with them and was obedient to them. But his mother treasured all these things in her heart. And Jesus grew in wisdom and stature, and in favor with God and people. - Luke 2:47-52 (NIV)
