Many of us, me included, will frequently fall into the trap of reading our Bibles merely to make observations about how godly people are supposed to act or how the godless people act and then rededicate ourselves to trying 
harder to be godlier and less godless. But, I’m becoming more and more convinced that we must realize the heroes we read about in the Bible are not perfect in anyway. They are not presented to us as examples we must try harder to follow. They are presented to us the way they are in the Old Testament so we’d more deeply appreciate the person, character, and work of Jesus Christ.
We must keep in mind what Paul says to us all. The obvious wickedness of blatant sinners is addressed in the first part of Romans, chapter 3. Then in Romans 3:9-12, Paul says, “Are we better than they? Not at all; for we have already charged that both Jews and Greeks are all under sin; as it is written, ‘THERE IS NONE RIGHTEOUS, NOT EVEN ONE; THERE IS NONE WHO UNDERSTANDS, THERE IS NONE WHO SEEKS FOR GOD; ALL HAVE TURNED ASIDE, TOGETHER THEY HAVE BECOME USELESS; THERE IS NONE WHO DOES GOOD, THERE IS NOT EVEN ONE.’” The capital letters here in the New American Standard Bible are showing us that Paul is quoting from the Old Testament. It’s not just the New Testament that teaches us that we’re all sinners. The Old Testament does also. Solomon understood this all along and told us so in Ecclesiastes. He says, “Indeed, there is not a righteous man on earth who continually does good and who never sins” (Ecclesiastes 7:20-21).
The heroes of the Bible were not righteous. Moses was not good enough! Joshua was not strong enough! The Judges were not brave enough! The kings were not even close to being righteous enough, and the priests were not pure enough. You see this is why we needed and still need a better “law keeper, a better judge, a better prophet, a better priest, and a better king.” Nancy Guthrie says, “Jesus must have looked Cleopas and his companion in the eyes that day and said, ‘That’s me. I’m the one the whole of the Old Testament points to. I’m the one God intended to send all along.’” There is ONE RIGHTEOUS! And it’s not me and it never will be me! It’s not you, and it never will be you! It’s HIM and only HIM!
