We are a vacuum. But we must admit that we are a vacuum, or we shall not be filled by the goodness of God. We must admit and constantly confess our emptiness, which is another word for humility. Mary declared how grateful she was that the Lord had done so much for Israel and His servant. Humility waits on others.
Humility responds to the bidding of the one whom it serves.
This is the mother of God, but only because she is also the lowly handmaid of the Lord. The more gifted a person, the more prone that person is to pride. Possession of anything naturally generates pride. And not only does possession generate pride, but the greater the possession the more pride it generates. Wealth of any kind inflates the human heart.
