5 “Behold, the days are coming, declares the Lord, when I will raise up for David a righteous Branch, and he shall reign as king and deal wisely, and shall execute justice and righteousness in the land. 6 In his days Judah will be saved, and Israel will dwell securely. And this is the name by which he will be called: ‘The Lord is our righteousness. Jeremiah 23: 5-6
The prophesy speaks about the “righteous Branch”. He is from “David” and He is “the Lord our righteousness.” In prophetic description, it teaches us that the Saviour is God and man. The union of God and man in righteousness realized in Jesus. That is our reason for worship and celebrate Christmas.
