What does Luke 1:27 mean?
This verse establishes important facts about Jesus' conception and birth. According to Old Testament prophecy, the Messiah would be miraculously born of a virgin (Isaiah 7:14). This would keep Jesus Christ free from inheriting original sin from Adam (Romans 5:12). This Promised One was also to be a family descendant of David (2 Samuel 7:12–16; Isaiah 9:6–7)."Betrothal," in Jewish culture, was a legally binding arrangement. Betrothed couples were promised to each other but did not live together nor consummate the relationship. At the end of the betrothal period, they would be formally married, and the woman would live with her new husband. Mary is an unmarried virgin, meaning she has never been intimate with any man (Luke 1:34).
Her soon-to-be husband is Joseph, part of the house of David (Matthew 1:1–17). His children, adopted or naturally born, would be part of the same tribe and family. Mary, as explained by Luke later in this gospel (Luke 3:23–38), is also a descendant of David.
The angel Gabriel has been sent (Luke 1:26) to deliver an incredible message to this young woman: she will miraculously become pregnant with the Son of God (Luke 1:31–33).
