In the city
He is the Christ,
ὅτι ἐτέχθη ὑμῖν σήμερον Σωτήρ, ὅς ἐστιν Χριστὸς Κύριος, ἐν πόλει Δαυείδ.
Luke then explained what the good news or the gospel proclamation was all about. A savior was born for them that day (ὅτι ἐτέχθη ὑμῖν σήμερον Σωτήρ) in the city of David (ἐν πόλει Δαυείδ). As they were on the outskirts of Bethlehem, they knew where the city of David was. This savior was the Christ (ὅς ἐστιν Χριστὸς), the Messiah, the Lord (Κύριος). Luke listed all the names that would be applied to Jesus. He was a savior, someone who would protect Israel. He was the Christ, the anointed one of God. He was the Messiah, the expected liberator of his people, the Israelites. He was the Lord, God, truly divine. This baby Jesus would be all these things rolled up into one. This was really big news.
