Genesis 18:1-5 KJV
1 And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;
2 And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,
3 And said, My Lord, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant:
4 Let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree:
5 And I will fetch a morsel of bread, and comfort ye your hearts; after that ye shall pass on: for therefore are ye come to your servant. And they said, So do, as thou hast said.

Genesis 18:16-33 KJV
16 And the men rose up from thence, and looked toward Sodom: and Abraham went with them to bring them on the way.
17 And the LORD said, Shall I hide from Abraham that thing which I do;
18 Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?
19 For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him.
20 And the LORD said, Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous;
21 I will go down now, and see whether they have done altogether according to the cry of it, which is come unto me; and if not, I will know.
22 And the men turned their faces from thence, and went toward Sodom: but Abraham stood yet before the LORD.
23 And Abraham drew near, and said, Wilt thou also destroy the righteous with the wicked?
24 Peradventure there be fifty righteous within the city: wilt thou also destroy and not spare the place for the fifty righteous that are therein?
25 That be far from thee to do after this manner, to slay the righteous with the wicked: and that the righteous should be as the wicked, that be far from thee: Shall not the Judge of all the earth do right?
26 And the LORD said, If I find in Sodom fifty righteous within the city, then I will spare all the place for their sakes.
27 And Abraham answered and said, Behold now, I have taken upon me to speak unto the Lord, which am but dust and ashes:
28 Peradventure there shall lack five of the fifty righteous: wilt thou destroy all the city for lack of five? And he said, If I find there forty and five, I will not destroy it.
29 And he spake unto him yet again, and said, Peradventure there shall be forty found there. And he said, I will not do it for forty's sake.
30 And he said unto him, Oh let not the Lord be angry, and I will speak: Peradventure there shall thirty be found there. And he said, I will not do it, if I find thirty there.
31 And he said, Behold now, I have taken upon me to speak unto the Lord: Peradventure there shall be twenty found there. And he said, I will not destroy it for twenty's sake.
32 And he said, Oh let not the Lord be angry, and I will speak yet but this once: Peradventure ten shall be found there. And he said, I will not destroy it for ten's sake.
33 And the LORD went his way, as soon as he had left communing with Abraham: and Abraham returned unto his place.

God converses with Abraham through out his life journey. Conversatiom as Abraham is not about Abraham's ability to control but asking God about his judgment. He not acting as Satan claiming of knowing someone will better. Satan went about testing God he wanted to destroy God's servant Job because God had blessed Job and thought Job would no longer respect God if he took his wealth from him. God told Satan he could do whatever he wanted to Job but he could not kill Job. Satan was testing man's commitment to God. Yet Abraham question with discourse that made him want to know how God judged man. Abraham gain knowledge how God judged evil and his people living in a place like Sodom and Gomorrah. His inquiry was based on not how man viewed his judgment but how God viewed his wrath on evil.

Go back a devotion read Satan's question and compare Abraham's question and ask how do you talk to God without understanding to gather insight of gaining knowledge of and understanding of God's judgment based on percentage in Abraham life verse Satan power to subtract and destroy God's chosen people without God explaining why he allowed Satan to destroy Job. Job was also without knowledge of Satan's inquiry or God given power given to Satan to try Job's faith.

If we want knowledge and understanding of God we must ask questions but not to prove God authority and power is finite not infinite.

Abraham concerned came because his nephew Lot and his family. The next chapter in Gensis will tell you about Lot's family journey out of Sodom and Gomorah, which allows you to know how many righteous people were still there. Let me jar your memory Abraham would have had knowledge of the flood though many hundred of years had past since the original story. His understanding of how God valued faithful people.

We are often looking at stories and judgment based on our own understanding about God. Abraham was asking questions to understand God's ways better. We as believers need to understand our understanding is finite and God"s ways are infinite.

Dear Heavenly Father give us understanding of your ways help to gain knowledge of who gou truly are. In Jesus precious name, Amen.
