One of the most painful experiences any family can have is to have a young child get lost, especially if it happens in a strange place. So it is not difficult to imagine the terrible distress that Mary and Joseph must have felt when they realised that Jesus was lost in a big city full of strangers for the feast. When they did find the Child, He told them that they should have known He was about His Father's affairs. It was another step in Mary's realisation that her Son was not fully hers and that He had a higher and more important mission. This was only the first intimation of future experiences - Jesus leaving home for His public life and ending in the terrible experience on the Cross. At the Annunciation Mary had said Yes to God's will and now she reflects on all this. "She treasured all these experiences in her (Immaculate) Heart." With Mary, let us also say an unconditional Yes to Jesus.
