All the kings of Israel and Judah failed to lead the people into righteousness because all of them, even the best, were fallen sinners who did not always rule wisely or righteously. Likewise, God's prophets, though they consistently called God's people to repentant and renewed faith, were never able to produce these things in the people to whom they preached God's Word. Thus, the kings and prophets of the Old Testament point out the need for a better king and a better prophet, one who rules in righteousness and makes his people righteous as well. Jesus is the perfect King and Prophet who perfectly meets that need.
