Genesis 18 – The LORD’s Visit: Abraham’s Hospitality, Sarah’s Promised Son, Intercession for Sodom, and the Righteous Judge (KJV Bible Study Chart)

Genesis 18 begins with the statement that “the LORD appeared unto” Abraham in the plains of Mamre. Abraham sees three men and immediately offers hospitality. Genesis 19 identifies two of these visitors as angels, while Genesis 18 repeatedly distinguishes the LORD as the One who remains and speaks with Abraham. Many Bible believers understand this appearance of the LORD as a pre-incarnate manifestation of Christ, though that conclusion comes from comparing Scripture rather than from an explicit statement in Genesis 18.

Abraham provides water, bread, a prepared calf, butter, and milk. His hospitality is genuine service, and Hebrews 13:2 provides an important comparison because it warns believers not to forget hospitality, since some have “entertained angels unawares.” Abraham’s encounter should not be described as Hebrews 13 promising that hospitality literally receives Christ; the passage specifically speaks of angels.

The LORD then asks about Sarah and announces that she will bear a son. Sarah laughs internally because of her age and Abraham’s age. The LORD immediately reveals that He knows her hidden response and asks, “Is any thing too hard for the LORD?” The promise of Isaac therefore rests on divine power rather than natural possibility. Romans 4 later emphasizes that Abraham believed God could perform what He had promised.

The chapter turns toward Sodom when the men rise and look in that direction. The LORD reveals the coming investigation and judgment because Abraham occupies a covenant position and will become a great nation. Scripture describes Sodom’s sin as “very grievous.” Other passages, including Ezekiel 16 and Genesis 19, supply additional details concerning the city’s pride, abundance, neglect of the poor, violence, and sexual wickedness.

The two angels proceed to Sodom while Abraham remains before the LORD. Abraham asks whether the righteous will be destroyed with the wicked and appeals to God’s own character: “Shall not the Judge of all the earth do right?” He begins with fifty righteous persons and gradually reduces the number to ten. At every stage, God demonstrates willingness to spare the city if the stated number of righteous people can be found.

Abraham’s prayer does not change an unjust God into a just one. Rather, his intercession rests upon the fact that God already is righteous. Genesis 19 will demonstrate that God can both judge the wicked and deliver the righteous, a truth later emphasized in 2 Peter 2.

Genesis 18 therefore presents promise, prayer, mercy, and judgment together. The LORD knows Sarah’s heart, confirms Isaac’s birth, hears Abraham’s plea, and remains perfectly righteous in judging Sodom. The chapter teaches that nothing is too hard for the LORD and that the Judge of all the earth will always do right.
