The answer is: Abraham

Gen 18:22-23

Abraham is quite a fascinating character in the Bible, known not just for his faith but also for his boldness in approaching God. When things got serious regarding the fate of Sodom, he didn’t shy away. Instead, like a skilled negotiator, he starts whittling down the potential threshold for saving the city, bargaining from fifty righteous souls down all the way to ten. This gives us a peek into both his compassion for the unjust and his burning desire for mercy over judgment.

Interestingly, Abraham's approach paints a vivid picture of intercession, which is a strong theme throughout scripture. It showcases the idea that when communities fail, it's often due to a loss of righteous individuals. It reflects how the collective morality of a city can resonate in God’s view, emphasizing the weight of individual actions in communal faith.

What’s also captivating is the concept of "righteousness," which ties back to similar moments in scripture. For example, Moses also interceded no less than three times for the Israelites when they strayed (see Exodus 32). This persistent attitude raises questions about the nature of divine judgment and mercy.

Moreover, Sodom’s ultimate demise has spawned countless discussions about justice and sin. Not only cries for justice a couple of millennia ago, but continues to spark debates in modern conversations about societal maladies. These stories unearth the roots of moral lessons that still resonate powerfully today, inviting us to reconsider our roles as avengers, guardians, and advocates in our own communities.
