God has been promising Abraham for twenty-five years that He will make him a great nation and a blessing to all the nations of the world. So far, Abraham has been left waiting and wondering about it all. Now, the time has come for God to begin making the promise a flesh-and-blood reality.
A CHILD IS BORN
Genesis 21:1-2 says,
The LORD visited Sarah as He had said, and the LORD did to Sarah as He had promised. And Sarah conceived and bore Abraham a son in his old age at the time of which God had spoken to him.
The Hebrew verb “paqad” is translated “visited” in this verse, but it is a strong verb that is difficult to translate. Far from a simple social call, it means here an action on the part of God which produces a beneficial result for His people. However, this verb is most often used in association with drawing up troops for battle. It is as though Sarah has been waiting all her life and now God has said, “It’s time now for you to get involved in My plan.” God had promised Abraham in Genesis 17:21 that Sarah would soon have a son and then He promised Sarah herself in chapter 18:14 that it was time. These verses and the preceding chapter involving Abimelech and his household make it clear that conception is the Lord’s doing. No child comes into the world apart from His action. Now this opens up a lot of questions for us because we simply can’t understand why good and loving women are sometimes not enabled to have children or why parents who neglect and abuse their children are allowed to have them in the first place. Just as Job did not understand why his situation was allowed to happen, neither do we understand all that God does or allows. However in the final chapters of Job, Job discovered that God was bigger than all of his “why’s” and so, like Job, we must let ourselves rest in God.
God is at last beginning to build a house for Abraham. Let’s look at Psalm 127 in connection with this idea of building a house.
Unless the LORD builds the house,
those who build it labor in vain.
Unless the LORD watches over the city,
The watchman stays awake in the vain.
It is in vain that you rise up early
And go late to rest,
Eating the bread of anxious toil;
for He gives to His beloved sleep.
Behold, children are a heritage from the LORD,
the fruit of the womb a reward.
Like arrows in the hand of a warrior
Are the children of one’s youth.
Blessed is the man
Who fills his quiver with them!
He shall not be put to shame
when he speaks with his enemies in the gate.
This Psalm works on the idea of building a house, guarding a city, and building a family. It points out that God is the true builder and watcher and without Him, our human labor is in vain. How does this relate to Abraham and Sarah? They had previously tried to build a family in their own way. Hagar and Ishmael were the result, and although Ishmael was a gift from God, he was also a symbol of man trying to work by his own common sense and effort in the strength of his own flesh.
Up to now, it seems that Sarah has not believed God. It was she who suggested the surrogate mother idea involving Hagar and when God finally told her it was time to have a baby, she laughed at the idea. So on the face of it, we wouldn’t think she had a lot of faith. But Hebrews 11:11-12 says,
By faith, Sarah herself received power to conceive, even when she was past the age, since she considered Him faithful Who had promised. Therefore from one man, and him as good as dead, were born descendants as many as the stars of heaven and as many as the innumerable grains of sand by the seashore.
So we see that Sarah herself was able to conceive because she believed God was faithful to His promises.
Verse 2 of Genesis 21 says that Sarah gave birth at the time God had told Abraham this would happen. Ecclesiastes 3:1-2 says, “For everything there is a season, and a time for every matter under heaven: a time to be born, and a time to die.” So we see that God had planned beforehand the exact time of Isaac’s birth. The times that God has set for all the things that happen on earth are a great mystery for us. We don’t understand why or when He does as He does. Romans 11:33 says, “Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are His judgments and how inscrutable His ways!”
OBSERVATION: Learn to rest in the mysteriousness of God, trusting in His goodness.
Returning to our text of study, Genesis 21:3 says, “Abraham called the name of his son who was born to him, whom Sarah bore him, Isaac.” The literal understanding of the name “Isaac” in this context is “God is Laughing Now.” In Genesis 17:17, Abraham laughed when God told him that Sarah would have a son. In Genesis 18:12, Sarah herself laughed when she heard God say that she would soon have a son. But God gets the last laugh. This is not a derisive or mocking laugh, but a laugh of joy.
Genesis 21:4-5 says,
And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. Abraham was a hundred years old when his son Isaac was born to him.
Notice here that Isaac was the first of the Hebrew line to be circumcised on the eighth day. Abraham was an old man and Ishmael a young boy when God made His official covenant with Abraham and instituted the rite of circumcision as a sign. The significance of the number 8 is that it marks a new beginning. The new week began on the eighth day and so the number 8 stands for new beginnings. Circumcision itself was meant to symbolize a new beginning, putting off the old nature that we are born with so that the new spiritual nature can be revealed. Now we see Isaac being circumcised on the eighth day, so something new is beginning. From Adam until Abraham, God dealt with man by means of his conscience. Eating of the Tree of Knowledge of Good and Evil aroused the conscience of Adam, so God worked through that for 2,000 years. Now He is getting ready to work through a nation, so we see that in Isaac, there is a new beginning in God’s dealings with man.
It is also important here to begin to look at Isaac through the eyes of Old Testament typology. In the past, God gave “pictures” in the lives of people that pre-figured Christ and also the Church and even in some cases God’s plan for future ages. This is what the scholars call “typology.” In the life of Isaac, we see a pre-figuring of Jesus. First, we see that both Isaac and Jesus were born by the promise of God. God promised Abraham and Sarah that He would give them Isaac. God promised the human race through Adam and Eve in Genesis 3:15 that He would send a Redeemer (the Seed of the woman) to destroy the work that Satan began in the Garden of Eden. Jesus was the fulfillment of that promise. Second, both Isaac and Jesus were born by supernatural intervention. Finally, they were born according to God’s pre-determined time. We have already mentioned this in connection with verse 1, but let’s look at Galatians 4:4-5. “But when the fullness of time had come, God sent forth His Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons.” So we see that the timing of the birth of Jesus was pre-determined by God.
GOD MAKES LAUGHTER
Genesis 21:5-7 continues,
Abraham was a hundred years old when his son Isaac was born to him. And Sarah said, "God has made laughter for me; everyone who hears will laugh over me." And she said, "Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age."
Verse 5 emphasizes the extreme age of Abraham. Hebrews 11:12 says that Abraham was so old he was “as good as dead.” In these verses regarding Sarah, we can feel some of the pain she must have endured for long decades as she watched other women having babies, nursing little ones and seeing them grow up around her, unable to identify with the pride and joy of the parents. She must have asked herself, “Why not me? What’s wrong with me?” Don’t we all sometimes ask ourselves, “Why do other people get all the lucky breaks? Why did that guy get a miraculous answer to prayer, but I didn’t?” I recently heard a person say, “I’ll believe in miracles when God tells me the winning lottery numbers!” To help correct our perspective on this, let’s look at Isaiah 54:1.
“Sing, O barren one, who did not bear;
break forth into singing and cry aloud,
you who have not been in labor!
For the children of the desolate one will be more
Than the children of her who is married,"
Says the LORD.
Sarah was barren except for one child, but she was blessed under the covenant of marriage, unlike Hagar. Like Sarah, we may not have a lot to show off in this life, but we are blessed under a covenant of grace with God Himself. What more do we want?
Sarah utters at this point what seems to me like a prophecy. She says, “All who hear of it will laugh.” This birth is good news for all people because through him, the Promised Redeemer will come. The angel in Luke 2:10, announcing the birth of Jesus, said, “Fear not, for behold, I bring you good news of great joy that will be for all the people.” The birth of Isaac was a foreshadowing of the great event announced by the angel.
Our text continues in Genesis 21:8, “And the child grew and was weaned. And Abraham made a great feast on the day that Isaac was weaned.” All is happy and joyous up to now. Isaac would have been about three years old when he was weaned and this was a first milestone in his development. The proud and happy parents are celebrating the life and growth of their son by proclaiming a feast. Likewise, in our own spiritual lives, after the life of the Son of God has been born into us when we trust Him for salvation, we are meant to nourish that new spiritual life with the milk of God’s word. The fellowship with other believers and the teaching, mentoring, and discipling of other more mature believers helps us to grow to the point that we can be spiritually “weaned” and begin to take on the solid meat of the word of God as His Spirit reveals truth to us. Just as every proud parent celebrates when a child becomes able to feed himself, those who watch over the spiritual lives of others rejoice when they begin to be able to understand God’s word and apply it for themselves. The Apostle Paul grieved over the failure of the Corinthian church to grow spiritually in I Corinthians 3:1-2 when he said, "But I, brothers, could not address you as spiritual people, but as people of the flesh, as infants in Christ. I fed you with milk, not solid food, for you were not ready for it. And even now you are not yet ready.”
TROUBLED WATERS
All seems happy and joyful, but a fly is about to land in the ointment in chapter 21, verses 9-11.
But Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, laughing. So she said to Abraham, "Cast out this slave woman with her son, for the son of this slave woman shall not be heir with my son Isaac." And the thing was very displeasing to Abraham on account of his son.
The party is in full swing when Sarah notices Ishmael laughing at Isaac. The word used here for laughter relates to Isaac’s name, but Ishmael is not rejoicing over Isaac—he is mocking his little brother. Ishmael is about 17 years old here and is probably jealous. It is easy to poke fun at the little fellow. Ishmael is strong, fast, and has probably been popular in the family all along. Isaac is toddling around, barely eating table food. So Ishmael relieves his jealous feelings by mocking little Isaac.
It’s important at this point to notice the typology of Isaac and Ishmael. Isaac is a type of the spiritual life and Ishmael is a type of the flesh. Isaac was born by the supernatural intervention of God but Ishmael was completely natural, born solely by the strength of the flesh. The flesh will always mock the spiritual. The flesh always seems smarter, more sophisticated, stronger, and ahead of the game, while the person who prays and waits for God to lead and move will seem weak and ineffective—at least for a time.
Sarah’s reaction is immediate, “Throw those two out!” This is obviously not a good moment of grace and tender mercy for Sarah. However, her instinct will be proved right. Abraham, we see, is unhappy with the idea. In this culture, dismissing a surrogate mother and her son was unthinkable. It also appears that Abraham loved Ishmael because he was his own son. So a bitter situation has developed here. What will Abraham do?
Genesis 21:12-13 continues,
But God said to Abraham, "Be not displeased because of the boy and because of your slave woman. Whatever Sarah says to you, do as she tells you, for through Isaac shall your offspring be named. And I will make a nation of the son of the slave woman also, because he is your offspring.”
When Sarah first suggested to Abraham the surrogacy scheme all those years ago, Abraham jumped right in with it. There is no record that he consulted with God at all. Here, however, he apparently spends the night seeking and listening to God regarding this problem. God’s response might seem a little surprising to us. He tells Abraham to do as Sarah said and send away Ishmael. But he consoles Abraham by telling him not to feel badly or worry about it. Although Isaac is the one through whom the promise will come, God promises to make Ishmael into a great nation because he, too, is Abraham’s son.
The Apostle Paul uses this occasion to illustrate the spiritual lesson seen in these two sons. Let’s look at Galatians 4:21-31.
Tell me, you who desire to be under the law, do you not listen to the law? For it is written that Abraham had two sons, one by a slave woman and one by a free woman. But the son of the slave was born according to the flesh, while the son of the free woman was born through promise. Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar. Now Hagar is Mount Sinai in Arabia; she corresponds to the present Jerusalem, for she is in slavery with her children. But the Jerusalem above is free, and she is our mother. For it is written, "Rejoice, O barren one who does not bear; break forth and cry aloud, you who are not in labor! For the children of the desolate one will be more than those of the one who has a husband." Now you, brothers, like Isaac, are children of promise. But just as at that time he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now. But what does the Scripture say? "Cast out the slave woman and her son, for the son of the slave woman shall not inherit with the son of the free woman." So, brothers, we are not children of the slave but of the free woman.
In this passage, we see that Isaac was born of a promise and thus typifies the spiritual, while Ishmael is born as an effort of the flesh and typifies the flesh. Paul uses this to illustrate that receiving Christ by faith under the new covenant is spiritual while keeping the law is an effort of the flesh. The Law itself acknowledges its inability to save from sin because it contains elaborate provisions for sacrifices for sin. But we see here that the flesh will always mock the Spirit. The world will always mock the faith of the believer. But sadly, within the Church, the carnal Christian will mock the spiritual Christian, because it will always seem that busy activity accomplishes more than prayer and waiting on God. It will also seem that injecting a little sensuality and worldliness into the church’s activities produces faster results than the simplicity of prayer, faith and resting in God.
THE PLACE FOR THE FLESH
Our text continues in Genesis 21:14-16:
So Abraham rose early in the morning and took bread and a skin of water and gave it to Hagar, putting it on her shoulder, along with the child, and sent her away. And she departed and wandered in the wilderness of Beersheba. When the water in the skin was gone, she put the child under one of the bushes. Then she went and sat down opposite him a good way off, about the distance of a bowshot, for she said, "Let me not look on the death of the child." And as she sat opposite him, she lifted up her voice and wept.
Notice that Abraham obeys God immediately. He gets up early the next morning and sends Hagar and Ishmael away with a little bread and water. He has God’s promise that Ishmael will prosper, so he trusts him into God’s hand and cuts ties at this point. Verse 15 tells us that Hagar wandered in the wilderness. She had no idea where to go. The wilderness is a place where you are definitely not in control. You are at the mercy of whatever comes along and there is no one to help you. If God doesn’t take care of you, you will die. It is a place where the proud are humbled and the humble are strengthened in their faith because they have no place to go but to God.
The lesson for us in all this is that the flesh must give way to the spiritual. Romans 13:14 says, “But put on the Lord Jesus Christ, and make no provision for the flesh, to gratify its desires.” Notice that the provisions sent for Ishmael were very meager. Jesus said, “If your right eye causes you to sin, tear it out and throw it away. For it is better that you lose one of your members than that your whole body be thrown into hell.” (Matthew 5:29) Likewise, Paul told the Corinthians, “I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified.” (I Corinthians 9:27) Once Christ has been born in us, He is to be the center of our attention. The flesh has to go. Notice also that if we will obey God by disciplining the flesh and “sending it away” figuratively, He will provide for it as He deems proper.
The story ends in verses 17-21:
And God heard the voice of the boy, and the angel of God called to Hagar from heaven and said to her, ‘What troubles you, Hagar? Fear not, for God has heard the voice of the boy where he is. Up! Lift up the boy, and hold him fast with your hand, for I will make him into a great nation.’ Then God opened her eyes, and she saw a well of water. And she went and filled the skin with water and gave the boy a drink. And God was with the boy, and he grew up. He lived in the wilderness and became an expert with the bow. He lived in the wilderness of Paran, and his mother took a wife for him from the land of Egypt.Here we see that the flesh, which generally seems so strong, is actually pitifully weak. Hagar and Ishmael don’t last long in the wilderness. That skin filled with water is now empty and Ishmael will soon be as dead as the skin itself if something doesn’t give. (Incidentally, the skin that held the water might be seen to typify the Law, unable with its system of sacrifice to impart the Living Water so essential to life.) This is all too painful for Hagar to bear, so she lays him down and goes off a little way. But something happens when she leaves Ishmael alone. Ishmael’s father is Abraham and he had heard all his life about the God of Abraham and he even saw Sarah having a baby at the age of 90, so as death closes in around him and his pride crumbles away, he calls out to God—and God hears him. In Ishmael’s brokenness, God hears and answers and saves him from death. God resists the proud, but gives grace to the humble (I Peter 5:5), so Ishmael in his repentance has found the place of grace.
In Genesis 16:10, God had promised Hagar that Ishmael would be greatly multiplied, and He renews that promise to her again. When we consider all the suffering that the descendants of Ishmael have caused the descendants of Isaac, we again find ourselves asking, “Why?” This remains another mystery in which we must rest and trust God. God opens Hagar’s eyes to another well. The well was there all along, but Hagar could not see it for herself.
QUESTION: How often are we too distracted with life to “see God?”
So we see that God did not abandon Ishmael after Abraham cut ties with him. While Ishmael stayed in the wilderness, God blessed and cared for him and made him mighty. If we will likewise reckon the fleshly things in our life as dead, God will then be free to make what He chooses of our physical lives.
Thanks for joining us. We are almost finished with our study of Abraham. Thanks for persevering.
