How do we know that sin is a reproach to any people?

Sin, described as the breach of God's law, results in the moral and spiritual decline of individuals and societies. The Scriptures, particularly in Isaiah 5:20, warn against calling good evil and evil good. When a nation embraces sin, it experiences judgment and disgrace, as it moves further away from God's standards. This degradation affects not only the nation as a whole but also families and churches, causing a ripple effect that diminishes righteousness and invites God's wrath upon the people.
