What does the Bible say about God's judgment on Sodom?

In Genesis 18, the Lord informs Abraham of His intent to judge Sodom due to the great cry against its sins, as stated in verses 20-21. This cry signifies not a plea for mercy but a demand for justice, reflecting the wickedness that had overtaken the city. God's judgment illustrates His holiness and the necessity of righteousness in a fallen world. Despite the impending destruction, this narrative also emphasizes God's merciful interaction with His chosen people, revealing that His judgment serves a purpose in His plan of redemption.
