Mary's Magnificat, recorded only in Luke's Gospel, is one of four hymns, distilled from a collection of early Jewish-Christian canticles, which complement the promise-fulfillment theme of Luke's infancy narrative.
In a style reminiscent of Old Testament poetry and song, Mary praises the Lord in alignment with this structure:
Mary rejoices that she has the privilege of giving birth to the promised Messiah (Luke 1:46–48).
She glorifies God for His power, holiness, and mercy (Luke 1:49–50).
Mary looks forward to God transforming the world through the Messiah. The proud will be brought low, and the humble will be lifted up; the hungry will be fed, and the rich will go without (Luke 1:51–53).
May you leap with joy just as Jesus cousin John (the Baptist) did in Elizabeth's womb when encountering the Christ child.
Prepare for the coming of Christ!
