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)
"When one abstains from false testimonies and shuns them and turns away from them, as sins, then from the Lord, through heaven, the love of truth and the love of justice flow in."
