After Mary consents to become the mother of Jesus she visits her relative Elizabeth, who is also expecting a baby, who will be John the Baptist. While there, Mary praises God, and speaks the words of the well known Magnificat. (Luke 1:39-56)
"Glorifying God...means to bring forth the fruits of love, that is, to perform the work of one's occupation faithfully, honestly, and diligently. For this is the effect of love of God and love of the neighbor."
