Luke 2:42

40 And the Child grew and became strong. He was filled with wisdom, and the grace of God was upon Him.

41 Every year His parents went to Jerusalem for the Feast of the Passover.

And when He was twelve years old, they went up according to the custom of the Feast.

43 When those days were over and they were returning home, the boy Jesus remained behind in Jerusalem, but His parents were unaware He had stayed.

44 Assuming He was in their company, they traveled on for a day before they began to look for Him among their relatives and friends.

Here the Bible tells a story about someone else. Ask yourself what it can say to us today. Do read the surrounding verses too, because the context often says more than a single verse.
