Behold, the days are coming,” declares the LORD,“When I will raise up for David a righteous Branch; And He will reign as king and act wisely And do justice and righteousness in the land. In His days Judah will be saved, And Israel will dwell securely; And this is His name by which He will be called, ‘The LORD our righteousness.’"-- Jeremiah 23:5-6
God promised He would raise up a "Righteous Branch," and He kept His promise when He sent Jesus. The Father knew our greatest need is a Savior. Without Him we would perish in our sin. We have in ourselves no righteousness. Nothing to recommend us to God and Heaven. It is only through Christ's righteousness that we are saved. "You will not find on this side heaven a holier people than those who receive into their hearts the doctrine of Christ's righteousness. When the believer says, 'I live on Christ alone; I rest on him solely for salvation; and I believe that, however unworthy, I am still saved in Jesus;' then there rises up as a motive of gratitude this thought - 'Shall I not live to Christ? Shall I not love him and serve him, seeing that I am saved by his merits?'" -- Charles Spurgeon. Rejoice in gratitude! The LORD is our righteousness!
