Genesis 21-24

Genesis 21-24

The story of Abraham offering up Isaac is usually studied om its own but there are lessons to be learnt from the stories of both Isaac and his firstborn Ishmael.
Chapter 20 shows us the last threat to the birth of Isaac, it comes from Abraham’s folly!
Chapter 21 tells us of Isaac’s birth and the crisis it causes in Abraham’s family Re:Hagar and Ishmael.
Chapter 22 narrates the test of Abraham’s faith.

 

1. Read 21:1-11. Isaac means “laughter.” (a) How is Sarah’s laughter here different from Gen 18:12? How does the annunciation support this? (Luke 1:35-37).

 As we saw in a previous study, Sarah’s laughter in 18:12 was a laughter arising from bitterness and unbelief: one was self-pity (“Old, useless me with child? What a joke!”) and one was an attack on God (“A ridiculous promise! You’ll never do it!”).
In Gen. 21:7 Sarah’s laughter is the exact opposite of that sneer. It is a laughter of joy in herself and confidence of God. This came about by God responding with a combination of rebuke and assurance. He asked, “Is anything too wonderful for the LORD?” (18:14). This rebuke for questioning God convicts Sarah of the sin of unbelief. God is saying, in effect, “I will do more than you can even imagine. I will fill your life with wonder.”
In 21:6, when Sarah says, “God has brought me laughter,” she now understands her joy is by the grace of God.

Our laughable weakness and God’s love strengthens us and  makes us rejoice deeply. The more we see how weak and undeserving we have been, the more his patience, love, and grace shine out and cause us to wonder. This is the gospel in plain sight.
Centuries later, an angelic messenger tells another woman about another miraculous birth and answers her doubt by saying, “For nothing is impossible with God” (Luke 1:37). Unless Isaac was born, the world cannot be blessed and saved (18:18), but ultimately Isaac is pointing to the one who turns our self-hatred to joy, Jesus Christ. “In Jesus we have the true Isaac, in whom we hear the laughter of God’s grace, triumphing over all impossibilities of our condition.” 3 Edmund Clowney

2. Read Gen 22:1-2 and 12:1-3. (a) How does the charge of Gen. 22 fit with his call in Gen. 12? Discuss this most severe test.

It is hard to miss the resonance of this call to Abraham with the first call in Genesis 12. Then and now he was called to “go” (21:2), leaving all his security and comfort behind. Then and now he is called to go without knowing the final destination. Then and now he was called to give his heart’s treasures as an “offering” to God. In Genesis 12, it was general. He was giving up friends and family and life in a safe place - major sacrifices. T To trust in God’s promise as his security and purpose, not the other things. In Gen 22 he is called to offer up Isaac, the dearest thing in his life. In each situation, “Focus on me alone” says the Lord. ‘Trust in me for your security, hope and joy.

Notice God’s emphasis in v2: “Your son, your only son”. Isaac is not literally Abraham’s only son. Isaac is Abraham’s only son with Sarah and all his hopes and promises are focused on him. God was saying, “Give up this…and wait for the promised son.” Isaac would certainly have been everything personally to Abraham. He was now very old.
But there is more, Isaac was the salvation the makings of a great nation that God had promised. But he was also the promised one through whom God’s blessing would come to the whole world. God is virtually saying, ‘Trust in me, though it looks like I am contradicting my own word!’ By faith, Abraham, when God tested him, offered Isaac. He who had received the promises was about to sacrifice his one and only son, although God had said to him, “It is through Isaac that your offspring will be reckoned.” (Heb. 11:18)

Footnote: Many have interpreted the moral of this story as: “God called Abraham to murder his son, and Abraham by faith and submission got ready to do it. So we should do whatever God calls us to do.” But this is a misunderstanding of the firstborn son in Judaism. If Abraham had heard a voice like God’s saying, “Go and kill Sarah,” he would not have done it, assuming that he was hallucinating and that God wouldn’t ask him to do something that was clearly wrong. But because of their sinfulness, the life of the Hebrew’s firstborn was forfeit, though they could redeem them with sacrifice (Ex. 22:29, 34:20) or Levitical service (Num. 3:40-41) or ransom payment (Num. 3:46-48). Remember how, God punished Egypt by taking their firstborn. The firstborn or heir was, in those traditions, the bearer of all the family’s hopes for a prosperous future. When God said that the child-heir’s life belonged to him unless ransomed, he was saying in the most vivid way possible that every family on earth owed a debt to eternal justice—the debt of sin. That is why God’s commandment to Abraham was enormously painful, but God was not asking him to murder his son. He was calling in Abraham’s debt! Abraham was faced with the question: “I do owe this. Our sin means that Isaac’s life is forfeit. Yet God is a God of grace as well. Can I trust a holy God to still graciously fulfil the promise?”

3. Read 22:3-8. Discuss Abraham’s thoughts and hopes as he goes to the mountain with Isaac?

Gen 22:8 and 5 show us that Abraham had to cling to the goodness and promises of God despite all logic. He says, “God…will provide the lamb” (v8). It is unlikely that he believed specifically that a ram-substitute would be discovered. Just that God would do it somehow. Do what? Somehow God would remove the debt on the firstborn and keep the promise of grace. “We will come back to you” (v5) implies Abraham has faith in God’s provision. The mountain path was still agony, as the dialogue shows in verses 6-8. Hebrews 11:19 suggests that Abraham even considered resurrection as a way that God could be both just and gracious. This is the ultimate test. Abraham was not just exercising blind faith. He wasn’t saying, “This is murder, but I’m going to do it anyway.” He was saying, “I know God is both holy and gracious. I don’t know how he is going to be both, but I know he will.” He had hope that God would do something up on the mount—and thus he trusted God.

4. Read 22:9-14. What provision did God make on the mountaintop that dealt with sin yet allowed Abraham to keep Isaac?

Abraham could not see the whole picture, he did see that God wanted faith: “Now I know that you fear God” (v12). Secondly, once he believed, God was able to provide a substitute for Isaac; he saw the “ram, caught by its horns” (v13). The New Testament writers knew what this was pointing to: first, Abraham’s sense of God-forsakenness was only symbolic. God did not truly forsake Abraham as he obeyed God in this ultimate test. But on the cross, when the ultimate beloved child cried, “My God, my God, why hast thou forsaken me?” “the Father paid the price in his silence,” Ed Clowney 5
Second, the true substitute for Isaac was God’s Son, Jesus, on the cross. 2 Chron 3:1 places Jerusalem in this region and God led his only Son into those hills. Wood was laid on this true Isaac. But there was no one to say, “Stay your hand.”  In Rom. 8:32, Paul understood the meaning of this story using its language to Jesus: “He who did not spare his own Son, but gave him up for us all—how will he not also, along with him, graciously give us all things?” Paul is saying look at Calvary and say to God, “Now,, we know that you love us, for you did not withhold your son, your only son, whom you love, from us.”

5. What lessons can we learn from the story of Isaac’s offering?

First, God will identify our idols and ask us to give them up. Isaac had become an idol, even in the midst of Abraham’s faith and obedience. Was Isaac more important than God to Abraham? Idols can be very subtle. For eg. we may consider spiritual activities and ministry as worthy rather than to God. These are “Isaacs” that God wants us to be willing to give up. Many idols are (like Isaac) good things that remain in our lives once we have handed them over to God. There they won’t control us leading to anxiety, pride, anger, and driven-ness. On the other hand, if Abraham had gone up the mountain thinking, “I just have to put him on the altar, not really giving him up,” he would have failed the test. Idols must cease to be idols. That is when we are really willing to live without them, trusting in God. Second, God seems to have forsaken us when he is near. Here he was saving the whole world and turning Abraham into a great man. We cannot know the reasons God allows bad things to happen, but, like Abraham, we must trust him. Abraham passed the test not with will power but by looking to the “provision” (22:8). Abraham had his eyes fixed on a provision he could not imagine but knew was there. But we can see the . As we look at the Lamb of God that takes away the sin of the world, and rejoice in what he did for us, we will have the joy and the freedom from idols and man-made securities to follow God’s call when it we cannot see the way ahead.

Conclusion

In the life of Abraham in Gen. 12 -22, we learn how God’s promises to Abraham began the redemption of the world. Gen 23-26 are a bridge between the story of Abraham and the story of Jacob (Gen 27-50).  Sarah dies in Chapter 23. Abraham finally becomes a landowner by acquiring a tomb for Sarah. In Gen 24, Abraham finds a wife for Isaac from his own relatives. God continues to work out his purposes and fulfil his promises in life and descendants of Isaac. Abraham dies in Gen 25 and Gen 26 is a series of snapshots from the life of Isaac. Isaac is overshadowed in the book of Genesis both by his father Abraham and his son Jacob. But even this brief look at Isaac shows God fulfilling his promises.
