Genesis 18 tells how the Lord visits Abraham by the oaks of Mamre in the form of three men, whom Abraham welcomes with generous hospitality. They repeat that Sarah will have a son within a year, and Sarah laughs inside the tent. Then the Lord announces judgment on Sodom and Gomorrah, and Abraham pleads that he not destroy the righteous with the wicked.
Genesis 18 combines two scenes: the visit at Abraham's tent, with the repeated promise of Isaac, and the dialogue about Sodom's fate. It is one of the most intimate chapters of the book, where God lets himself be seen as guest and friend, and where Abraham learns to pray boldly and humbly for others.
The Lord appears to Abraham by the oaks of Mamre as he sits at the door of his tent in the heat of the day. Looking up, he sees three men standing in front of him, and he runs to meet them, bows low and asks them to stay and rest. He tells Sarah to make bread with fine flour, takes a tender calf himself and gives it to a servant to prepare, and serves them curds, milk and the calf as they eat under the tree.
The visitors ask about Sarah and tell him that in a year she will have a son. Sarah hears from the tent and laughs, thinking she is old. The Lord asks why she laughed and whether anything is too hard for the Lord. Sarah, afraid, denies that she laughed, but the Lord tells her that she did.
The men rise to go toward Sodom, and Abraham walks with them. The Lord decides not to hide from Abraham what he is about to do, because he has chosen him so that he will teach his children the way of the Lord, doing righteousness and justice. He announces that the outcry against Sodom and Gomorrah is great and that he will go down to see. The men go on toward Sodom, but Abraham remains standing before the Lord and draws near. He asks whether he will sweep away the righteous with the wicked, and pleads humbly: if there are fifty righteous, then forty-five, forty, thirty, twenty and ten. The Lord answers that for the sake of ten he will not destroy it. When he finishes speaking with Abraham, the Lord goes his way, and Abraham returns to his place.

Abraham looks up and sees three men standing there, runs to meet them and bows. Without yet knowing who they are, he treats strangers with a hospitality that the New Testament later recalls as a virtue.
The Lord asks whether anything is too hard for him, and repeats that in a year Sarah will have a son. God's answer to Sarah's laughter is a question that remains valid for every doubt: his power has no limit.
The Lord says he has chosen Abraham so that he will command his children and household to keep the way of the Lord, doing righteousness and justice. Abraham's election has a moral purpose: to form a people who live by God's justice.
Abraham asks whether the Judge of all the earth will not do what is just. His prayer rests on God's character and shows that we can pray with frankness while still recognizing the Lord's authority and justice.

Genesis 18 invites us to generous hospitality. Abraham did not know whom he was welcoming, but he gave the best he had. In a group you can ask how we receive visitors to our church and what cost we are willing to bear in order to care for others.
It also teaches intercessory prayer. Abraham did not stand by watching judgment fall: he drew near to God on behalf of others. Ask for whom you need to intercede, even if your city, your family or your workplace seem far from God, and how to trust that the Judge of all the earth always acts with justice and mercy.
Genesis 18 ends with Abraham returning to his place, and with the fate of Sodom still pending. In Genesis 19 the two companions will arrive at the city, and we will see what happened to Lot and his family.
The text says the Lord appeared and that Abraham saw three men. Later two of them are called angels in Genesis 19:1, and one speaks as the Lord himself. Many Christians see in the passage an appearance of the Lord accompanied by two angels.
She laughed in disbelief at the thought of her old age and her husband's. She denied it out of fear. The Lord does not reject her but repeats his promise and reminds her that nothing is too hard for him, and the son will be named Isaac, a name that recalls that laughter.
More than bargaining, Abraham is interceding. His persistence shows that he believes God is just and wants to save the innocent. The dialogue also reveals God's patience, who answers each request without anger, and his willingness to forgive a city for the presence of a few righteous people.
