Key Verses: Genesis 18:10, 18:14, 18:19, 18:25
The LORD appears to Abraham by the oaks of Mamre as three men approach. Abraham bows, offering hospitality-water to wash feet, rest under the tree, a morsel of bread. They accept. Abraham hurries to Sarah for cakes, runs to select a calf, and prepares a feast. They eat under the tree. One asks where Sarah is; Abraham says in the tent. He says, “I will surely return to you about this time next year, and Sarah shall have a son.” Sarah, listening at the tent door, laughs inwardly-she’s old and past childbearing. The LORD asks Abraham why Sarah laughed, doubting God can do this. “Is anything too hard for the LORD?” Sarah denies laughing out of fear. The men depart toward Sodom. The LORD contemplates whether to hide from Abraham what He’s about to do-destroy Sodom. Abraham will become a great nation, and God has chosen him to command his children to keep the LORD’s way by doing righteousness and justice. The LORD reveals Sodom and Gomorrah’s grave sin. Abraham intercedes: “Will you destroy the righteous with the wicked?” Would God spare the city for 50, 45, 40, 30, 20, or 10 righteous? Each time God agrees, but Abraham realizes there aren’t even ten.
This chapter beautifully displays the Trinity-the LORD appears as three visitors (Genesis 18:1), yet Abraham addresses “My Lord” (singular, 18:3), and the LORD speaks (18:13). The three are distinct yet one. Sarah’s laughter shows unbelief; God graciously confronts it. “Is anything too hard for the LORD?” encapsulates the chapter’s theme-God accomplishes the impossible. Abraham’s intercession for Sodom demonstrates boldness in prayer, grounded in God’s justice and mercy. His question, “Shall not the Judge of all the earth do what is just?” affirms God’s perfect righteousness. God reveals His plans to Abraham because of covenant relationship (18:17-19). This prefigures Christ’s friendship with disciples (John 15:15). Abraham’s failure to find even ten righteous in Sodom justifies judgment. His intercession foreshadows Christ’s greater intercession.
