The Father does not delay, but He will act only after Our Lady has prepared the world. By standing at the cross, Mary prepared for the Father’s action of raising Jesus from the dead. At the second hour, she prepares the world for the Father’s special sending of Jesus.
Mary is the new John the Baptist. She has accepted this command, assumed her responsibilities and embarked on her mission. No one can stop her. Even the Roman soldiers could not keep her away from the cross.
