Genesis 18:20-33 New International Version (NIV)
20 Then the Lord said, “The outcry against Sodom and Gomorrah is so great and their sin so grievous 21 that I will go down and see if what they have done is as bad as the outcry that has reached me. If not, I will know.”
22 The men turned away and went toward Sodom, but Abraham remained standing before the Lord.[a] 23 Then Abraham approached him and said: “Will you sweep away the righteous with the wicked? 24 What if there are fifty righteous people in the city? Will you really sweep it away and not spare[b] the place for the sake of the fifty righteous people in it? 25 Far be it from you to do such a thing—to kill the righteous with the wicked, treating the righteous and the wicked alike. Far be it from you! Will not the Judge of all the earth do right?”
26 The Lord said, “If I find fifty righteous people in the city of Sodom, I will spare the whole place for their sake.”
27 Then Abraham spoke up again: “Now that I have been so bold as to speak to the Lord, though I am nothing but dust and ashes, 28 what if the number of the righteous is five less than fifty? Will you destroy the whole city for lack of five people?”
“If I find forty-five there,” he said, “I will not destroy it.”
29 Once again he spoke to him, “What if only forty are found there?”
He said, “For the sake of forty, I will not do it.”
30 Then he said, “May the Lord not be angry, but let me speak. What if only thirty can be found there?”
He answered, “I will not do it if I find thirty there.”
31 Abraham said, “Now that I have been so bold as to speak to the Lord, what if only twenty can be found there?”
He said, “For the sake of twenty, I will not destroy it.”
32 Then he said, “May the Lord not be angry, but let me speak just once more.What if only ten can be found there?”
He answered, “For the sake of ten, I will not destroy it.”
33 When the Lord had finished speaking with Abraham, he left, and Abraham returned home.
God let Abraham question him, his justice, and he allowed for intercession. Abraham knew God must punish sin. He also knew that God is merciful to sinners. God already knew there were not 10 people who were innocent in the city, but God let Abraham intercede. God was also merciful and allowed Lot and his family to get out of the city before it was destroyed. God does not take pleasure in destroying the wicked, but he must punish sin. God is merciful and just, and his mercy extends to you.
