When David stood at the other end of Nathan’s boney finger, pointed directly in his face—he was guilty, and he knew it. David had broken every law in the book, God’s Book.
In reality, David had broken all of the Ten Commandments when he sinned with Bathsheba. How had he broken them all? In two ways; first by his actions he broke them all. And secondly, by God’s standards he broke them all.
The good news is that Jesus died for all of us who are guilty sinners. As we read the rest of this Psalm and see how David asked for the sacrificial death of another to be counted for him (purge me with hyssop)—we can see why Christ’s death for us sinners is so precious, and so powerful.
