"And all who heard it wondered at what the shepherds told them. But Mary treasured up all these things, pondering them in her heart." Luke 2:18-19
There was quite a buzz going around about Jesus' birth. When the angels appeared and the glory of the Lord shone down, the shepherds found the Baby in Bethlehem and it all checked out. They spread the word, and people were blown away.
Years later, when the adult Jesus went public with his ministry, the response was not, "We've been waiting for you." The response was, "Is not this Joseph's son?" (Luke 4:22). They had forgotten.
But Mary treasured up all these things, pondering them in her heart. "Treasured up" means that she prized and guarded and preserved in her thoughts everything that happened. "Pondering" means that she began connecting the dots between the Old Testament prophecies and now these astounding events, reaching by faith for what it all meant.
The crowds were fascinated. That was not wrong. It was right. But it didn't last. And it didn't change them. But Mary went into sustained reflection and meditation and growing understanding.
