What if an ordinary day, a simple act of kindness, brought you face-to-face with the Divine? Genesis 18 thrusts Abraham into such a moment. Mysterious visitors arrive, YHWH’s promise of a son defies human biology, and Sarah laughs at what she believes must be impossible. But then, the conversation shifts. The strangers are from God—even the preincarnate Son of God Himself accompanied by two angels—and God reveals impending judgment against Sodom and Gomorrah. Abraham, in astonishing boldness, begins to intercede. How close can humanity draw to God? Can we truly plead for mercy against divine justice? Is anything too hard for the Lord, and how does He respond when we dare to ask?

The Rev. Robert Smith, pastor emeritus in Ft. Wayne, IN, joins the Rev. Dr. Phil Booe to study Genesis 18.

Genesis isn’t just the start of the Bible; it’s the foundation of everything. Creation, sin, judgment, grace, covenant, and promise all take root in this remarkable book. The stories are ancient, but their truths are eternal.

In this new series from Thy Strong Word, Pastor Phil Booe and his guests walk verse by verse through Genesis, exploring how God reveals Himself as Creator, Judge, and Redeemer. From the grandeur of the cosmos to the struggles of ordinary families, Genesis introduces us to a God who speaks, acts, and keeps His promises. So, whether you’ve read it a hundred times or are just now cracking it open for a serious look, this series will help you see Genesis with fresh eyes—and a deeper faith.

Thy Strong Word, hosted by Rev. Dr. Phil Booe, pastor of St. John Lutheran Church of Luverne, MN, reveals the light of our salvation in Christ through study of God’s Word, breaking our darkness with His redeeming light. Each weekday, two pastors fix our eyes on Jesus by considering Holy Scripture, verse by verse, in order to be strengthened in the Word and be equipped to faithfully serve in our daily vocations.

Genesis 18

18 And the Lord appeared to him by the oaks[a] of Mamre, as he sat at the door of his tent in the heat of the day. 2 He lifted up his eyes and looked, and behold, three men were standing in front of him. When he saw them, he ran from the tent door to meet them and bowed himself to the earth 3 and said, “O Lord,[b] if I have found favor in your sight, do not pass by your servant. 4 Let a little water be brought, and wash your feet, and rest yourselves under the tree, 5 while I bring a morsel of bread, that you may refresh yourselves, and after that you may pass on—since you have come to your servant.” So they said, “Do as you have said.” 6 And Abraham went quickly into the tent to Sarah and said, “Quick! Three seahs[c] of fine flour! Knead it, and make cakes.” 7 And Abraham ran to the herd and took a calf, tender and good, and gave it to a young man, who prepared it quickly. 8 Then he took curds and milk and the calf that he had prepared, and set it before them. And he stood by them under the tree while they ate.

9 They said to him, “Where is Sarah your wife?” And he said, “She is in the tent.” 10 The Lord said, “I will surely return to you about this time next year, and Sarah your wife shall have a son.” And Sarah was listening at the tent door behind him. 11 Now Abraham and Sarah were old, advanced in years. The way of women had ceased to be with Sarah. 12 So Sarah laughed to herself, saying, “After I am worn out, and my lord is old, shall I have pleasure?” 13 The Lord said to Abraham, “Why did Sarah laugh and say, ‘Shall I indeed bear a child, now that I am old?’ 14 Is anything too hard[d] for the Lord? At the appointed time I will return to you, about this time next year, and Sarah shall have a son.” 15 But Sarah denied it,[e] saying, “I did not laugh,” for she was afraid. He said, “No, but you did laugh.”

16 Then the men set out from there, and they looked down toward Sodom. And Abraham went with them to set them on their way. 17 The Lord said, “Shall I hide from Abraham what I am about to 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 have chosen[f] him, that he may command his children and his household after him to keep the way of the Lord by doing righteousness and justice, so that the Lord may bring to Abraham what he has promised him.” 20 Then the Lord said, “Because the outcry against Sodom and Gomorrah is great and their sin is very grave, 21 I will go down to see whether they have done altogether[g] according to the outcry that has come to me. And if not, I will know.”

Abraham Intercedes for Sodom

22 So the men turned from there and went toward Sodom, but Abraham still stood before the Lord. 23 Then Abraham drew near and said, “Will you indeed sweep away the righteous with the wicked? 24 Suppose there are fifty righteous within the city. Will you then sweep away the place and not spare it for the fifty righteous who are in it? 25 Far be it from you to do such a thing, to put the righteous to death with the wicked, so that the righteous fare as the wicked! Far be that from you! Shall not the Judge of all the earth do what is just?” 26 And the Lord said, “If I find at Sodom fifty righteous in the city, I will spare the whole place for their sake.”

27 Abraham answered and said, “Behold, I have undertaken to speak to the Lord, I who am but dust and ashes. 28 Suppose five of the fifty righteous are lacking. Will you destroy the whole city for lack of five?” And he said, “I will not destroy it if I find forty-five there.” 29 Again he spoke to him and said, “Suppose forty are found there.” He answered, “For the sake of forty I will not do it.” 30 Then he said, “Oh let not the Lord be angry, and I will speak. Suppose thirty are found there.” He answered, “I will not do it, if I find thirty there.” 31 He said, “Behold, I have undertaken to speak to the Lord. Suppose twenty are found there.” He answered, “For the sake of twenty I will not destroy it.” 32 Then he said, “Oh let not the Lord be angry, and I will speak again but this once. Suppose ten are found there.” He answered, “For the sake of ten I will not destroy it.” 33 And the Lord went his way, when he had finished speaking to Abraham, and Abraham returned to his place.
