The answer is: Nathan

2 Sam 12:1 - David sent Uriah into battle to be killed so he could take Bathsheba as his wife

In the story of King David, Nathan playing the role of God's messenger is a fascinating passage. He arrives on the scene as a truth-teller, serving as a prophet to confront King David—this might seem like a risky move, especially since David had the power to execute him! But Nathan didn't shy away from delivering God’s message. He used a clever story about a rich man who stole a poor man's only sheep to draw David in, only for David to realize that he was the one truly at fault. It’s a classic demonstration of how a story can reveal deeper truths, compelling even a king to examine his actions.

This narrative gives a glimpse into how accountability operates in the divine-human relationship: God doesn't leave David to wallow in his guilt alone, but sends Nathan to offer not just rebuke but also an opportunity for repentance. Fun fact: Nathan appears later in 1 Kings as an adviser in securing Solomon's place on the throne, which shows that he remained a prominent figure in David's circle!

The tragic fallout from David's actions resembles events throughout biblical history, where leaders face consequences for their moral lapses. Such cycles underscore a central theme: the heart poses great risk, and leadership comes with immense responsibility. Through Nathan's courageous confrontation, we see that truth—as uncomfortable as it may be—is crucial in leading one back to righteousness.
