We underestimate and under-use our Guardian Angels.
Here is St. Bernard on my angel and his angel, and your angels: "For he is a domestic, a familiar in the palace, having no fear of meeting with a repulse, and daily seeing the 'Face of the Father'".
Goodness. My angel goes back and forth into the House of God, into the Beatific Vision. If I ask this servant, who knows and loves His Master, and to whom His Master listens, how can I doubt that my prayers will be answered?
A servant of love goes to Love and asks for love. Ask your angel for a Christmas present of love.
