Ping!
Well done, NYer.
Mary was blessed because she was the “natural” part of man (humanity) which God needed to create Jesus.
Because, Jesus had to be part man (human), in order to redeem man (humans). If Jesus has been ONLY diety, HE COULD NOT HAVE BEEN OUR SAVIOR.
Mary was a very precious young woman who loved God.
She may not have known what Jesus was really up to when she conceived him and bore him; but after his death, she was in the upper room with all the Apostles where she also received the Baptism of the Holy Spirit like the rest of the group. How excited she must have been.
