A. Abraham meets some very important visitors.
1. (1-5) Abraham invites the Lord and two others to a meal.
Then the Lord appeared to him by the terebinth trees of Mamre, as he was sitting in the tent door in the heat of the day. So he lifted his eyes and looked, and behold, three men were standing by him; and when he saw them, he ran from the tent door to meet them, and bowed himself to the ground, and said, "My Lord, if I have now found favor in Your sight, do not pass on by Your servant. Please let a little water be brought, and wash your feet, and rest yourselves under the tree. And I will bring a morsel of bread, that you may refresh your hearts. After that you may pass by, inasmuch as you have come to your servant." They said, "Do as you have said."
a. Then the Lord appeared: Apparently, this happened a short time later. In Genesis 17:21, God said Sarah would give birth one year later, and at this time, she is not yet pregnant. So this couldn't be more than three months after the events in Genesis 17.
b. Then the Lord appeared to him by the terebinth trees: Here again, the Lord came to Abraham in human appearance. This is another presentation of Jesus in human form before His incarnation.
i. We can assume that this was God, in the Person of Jesus Christ, appearing to Abraham before His incarnation and birth at Bethlehem. We assume this because of God the Father it says, No one has seen God at any time. The only begotten Son, who is in the bosom of the Father, He has declared Him (John 1:18), and no man has ever seen God in the Person of the Father (1 Timothy 6:16). Therefore, if God appeared to someone in human appearance in the Old Testament (and no one has seen God the Father) it makes sense the appearance is of the eternal Son, the Second Person of the Trinity, before His incarnation in Bethlehem.
c. Behold, three men were standing by him: We don't know if Abraham immediately recognized who these visitors were. Though the Lord (in the Person of Jesus Christ) appeared to Abraham twice before (Genesis 12:7, 17:1), we don't know if Jesus looked the same each time, or if Abraham could just know who this was.
d. He ran from the tent door to meet them: According to his godliness and the customs of that culture, Abraham offered the hospitality of his house to these travelers.
2. (6-8) Sarah and Abraham prepare a meal for their visitors.
So Abraham hurried into the tent to Sarah and said, "Quickly, make ready three measures of fine meal; knead it and make cakes." And Abraham ran to the herd, took a tender and good calf, gave it to a young man, and he hastened to prepare it. So he took butter and milk and the calf which he had prepared, and set it before them; and he stood by them under the tree as they ate.
a. Abraham hurried into the tent: Again, to us this may seem to be overdoing it, but ancient culture had an extremely strong sense of hospitality to visitors. And it is also likely Abraham knew it was the Lord visiting him.
3. (9-10) God reconfirms His promise of a son.
Then they said to him, "Where is Sarah your wife?" So he said, "Here, in the tent." And He said, "I will certainly return to you according to the time of life, and behold, Sarah your wife shall have a son." (Sarah was listening in the tent door which was behind him.)
a. I will certainly return to you according to the time of life, and behold, Sarah your wife shall have a son: We may wonder why God repeated the promise again, so close to the time when He said it previously. After all, it seems God was silent about the promise for more than 13 years. Now He came personally to repeat it twice in three months.
b. Sarah your wife shall have a son: We need to hear God's promises over and over again. It is a way God uses to encourage and develop our faith: So then faith comes by hearing, and hearing by the word of God (Romans 10:17).
i. Perhaps also, Abraham and Sarah needed this visit to be an encouragement for them to do what they needed to do in bringing God's promise to pass - to have sexual relations.
4. (11-12) Sarah's reaction to God's promise.
Now Abraham and Sarah were old, well advanced in age; and Sarah had passed the age of childbearing. Therefore Sarah laughed within herself, saying, "After I have grown old, shall I have pleasure, my lord being old also?"
a. After I have grown old, shall I have pleasure? Sarah laughed within herself at this promise. She could not believe God would literally grant this child as the result of normal sexual relations.
i. Leupold translates Genesis 18:12, "After I have become worn out, have I enjoyed sexual delight and my lord too is an old man?" Leupold the observes, "The matter is not put very delicately by Sarah."
ii. It may be, even after the dramatic promises of Genesis 17, Abraham and Sarah had a way of "spiritualizing" God's promise, making it mean something other than what God intended. Here, God made it plain: Abraham and Sarah will have normal sexual relations and produce a baby.
iii. It is strangely characteristic of us to believe God's promise for a long, long, time, and endure through much discouragement along the way, until the promise is almost there, and then we find doubt. We are grateful that He is greater than our doubts.
b. Sarah had passed the age of childbearing: By all outward circumstance, there was good reason for Sarah to "spiritualize" the promise and laugh at its literal meaning. She had passed the age of childbearing, which literally seems to mean, "the manner of women had ceased to be with Sarah." She had stopped menstruating and had gone through menopause.
i. Even accounting for their long lives (Abraham lived to be 175 and Sarah 127), they were both well past middle age. It would take a miracle of God for them to have literal children through normal means.
c. Therefore Sarah laughed within herself: Significantly, this is what Sarah (and Abraham) most wanted all their lives. Yet, they find it so hard to believe God's promise when He says He will grant it to them.
5. (13-15) God answers Sarah's laugh.
And the Lord said to Abraham, "Why did Sarah laugh, saying, 'Shall I surely bear a child, since I am old?' Is anything too hard for the Lord? At the appointed time I will return to you, according to the time of life, and Sarah shall have a son." But Sarah denied it, saying, "I did not laugh," for she was afraid. And He said, "No, but you did laugh!"
a. Why did Sarah laugh: God heard Sarah's laugh even though she laughed within herself. There was nothing hidden before the Lord.
i. We might live very differently if we remembered that God hears and knows everything we think and say.
b. At the appointed time I will return to you: We might think God would say, "I gave you this promise twice and twice you laughed at it. That's it! No more promise. I'll take it to someone who will appreciate it." Instead, God responded by dealing with her sin of unbelief, but not by taking away the promise.
i. If we are faithless, He remains faithful; He cannot deny Himself (2 Timothy 2:13).
c. Is there anything too hard for the Lord? Thankfully not, and God can also triumph even over our weak faith.
i. Hard is the same word for wonderful in Isaiah 9:6: For unto us a Child is born, Unto us a Son is given . . . And His name will be called Wonderful. Jesus is our "wonderful" One, and He isn't to hard or wonderful for God to give unto us.
d. The Lord said to Abraham: Significantly, God dealt with Abraham about this, not Sarah herself, because Abraham was the head of his home.
B. Abraham intercedes for the cities of Sodom and Gomorrah.
1. (16-19) God decides to reveal to Abraham the fate of Sodom and Gomorrah.
Then the men rose from there and looked toward Sodom, and Abraham went with them to send them on the way. And the Lord said, "Shall I hide from Abraham what I am doing, since Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him? For I have known him, in order that he may command his children and his household after him, that they keep the way of the Lord, to do righteousness and justice, that the Lord may bring to Abraham what He has spoken to him."
a. Abraham went with them to send them on the way: As would be customary for a hospitable host in that day, Abraham will accompany his guests on their journey for a while as they depart.
b. Shall I hide from Abraham what I am doing: Because of what God would bring from Abraham (a great and mighty nation), and because Abraham had to be a great leader (that he may command his children and his household after him), God will reveal to Abraham what He will do with Sodom and Gomorrah.
i. This point is vital; God's purpose in this is not "gossip" with Abraham about what He will do, nor is it to satisfy Abraham's curiosity. God wanted to do something in Abraham's life through what He will reveal to him.
2. (20-21) God tells Abraham He will see if Sodom and Gomorrah are worthy of judgment.
