Luke 1:76-78
Zechariah moved from praising God directly, to addressing his son, John. As God's prophet, he will prepare the way for the Lord's coming (Isa 40:3). He will prepare the way by giving knowledge of salvation to Israel. This knowledge was neither abstract nor theoretical. It was something learned by experience. It was seen in the forgiveness of their sins (3:3, 7-8). This is the essence of God's saving mercy in Jesus. It is one of the central themes of Christianity (see 4:18; 24:47; Acts 2:38; 5:31; 10:43; 13:38). See BC 22.
