The Lord Jesus Christ is the only king of righteousness and peace for the church (see Isaiah 9:6; 32:1-2). Christ is not only a righteous and peaceable king, as were his types, Melchizedek and Solomon, but he is the author and dispenser of righteousness and peace to the church. "'The days are coming,' declares the LORD, 'when I will raise up to David a righteous Branch, a King who will reign wisely and do what is just and right in the land. In his days Judah will be saved and Israel will live in safety. This is the name by which he will be called: The LORD Our Righteousness" (Jeremiah 23:5-6). Christ is righteous and reigns righteously; but this not all, he is "the LORD Our Righteousness."
