Many Christians know that David wrote roughly half of the psalms recorded in the Old Testament. And most also know that David committed wretched sins that he repented of before the Lord. But fewer understand how the life, ministry, and kingship of David play a vital role in the story of the coming Messiah that unfolds in the Old Testament. The Scriptures teach that the Messiah would be a descendent of David and that He will reign forever on his throne.
