Luke 2:11 for today in the city of David there has been born for you a Savior, who is Christ the Lord.
But in this usage it's way beyond that. When it says this is the Savior who is Christ the Lord, you'll notice and it will be true every time it's used in the Bible to speak of Jesus Christ or of God, it's a capital "L". You're not seeing it here as some human designation, you're seeing this as a divine designation. To say that this child is Lord, listen very carefully, is to say that this child is God. Lord is intended to imply in the Greek all that is implied by the Hebrew word Yahweh, the tetragrammaton, the Hebrew name for God. To say that Jesus is Lord is to say that Jesus is God first and foremost. And let me say this as clearly and simply as I can and you need to remember this, the most fundamental and basic confession of Christianity is this, Jesus is Lord. That is the most fundamental and basic confession of the Christian faith. Without that you don't have Christianity.
