What does Luke 1:74 mean?
The prior verse mentioned an "oath" which God swore to Israel's patriarchs, starting with Abraham (Genesis 22:16–18). Among the promises delivered by God's prophets was the arrival of a Messiah (Isaiah 9:6–7), who would establish ultimate victory over sin and evil. One result of this Savior's work would be an end to Israel's persecution from the world and its resulting fear. Prophets like Zephaniah looked forward to that day (Zephaniah 3:14–17).This verse is part of a celebration of God's fulfillment of some of those guarantees. Zechariah, a priest, knows his son (Luke 1:13–17, 57) will be a herald appointed by God (Isaiah 40:3; Malachi 3:1; 4:6). This child, John the Baptist (Luke 3:2–3), will prepare the world for Jesus Christ (Luke 1:31–33). Zechariah and his wife, Elizabeth, are aware that Jesus' birth will happen soon (Luke 1:39–45). The prophetic song given by Zechariah (Luke 1:67–68) intertwines references to the Old Testament with confidence that God's promises continue to come true.
