Why Did God Ask Abraham to Sacrifice Isaac?

John Harden

In a previous article we asked, “Does God Command Evil Actions in the Bible?” We saw that God “is in no way to be considered the direct or indirect cause of evil” (Catechism of the Catholic Church 311). So it would not make sense for him to ask anyone to act in an evil way. So then why does God tell Abraham, “Take your son Isaac, your only one, whom you love, and go to the land of Moriah. There offer him up as a burnt offering on one of the heights that I will point out to you” (Genesis 22:2)? How can God ask Abraham to offer his own son as a human sacrifice? As we saw in the first question, context is key. To understand what is happening in Genesis 22 we need to see what happened in Genesis 21.

This Isn’t the First Time Abraham Was Asked to Sacrifice a Son

Isaac was not the first son born of Abraham, but he was the first son born to his wife, Sarah. After bearing Isaac, Sarah wanted nothing to do with Abraham’s other son, Ishmael. So she commanded Abraham, “Drive out that slave and her son! No son of that slave is going to share the inheritance with my son Isaac” (Genesis 21:10)! It’s ironic that Sarah asks for this, considering it was her idea for Abraham to sleep with “that slave girl” (see Genesis 16:2). What’s more shocking is what Sarah’s command implies. Hagar was a slave with no one to turn to for help. Being sent away from Abraham’s provision and protection was essentially a death sentence for her and Ishmael.

God reassured Abraham, “Do not be distressed about the boy or about your slave woman. Obey Sarah, no matter what she asks of you; for it is through Isaac that descendants will bear your name. As for the son of the slave woman, I will make a nation of him also, since he too is your offspring” (Genesis 21:12-13). At this point Abraham has learned to trust God. He knows God’s word is true, and so he knows Ishmael will live, and Isaac will be the father of his descendants. So he does as he was told, and sends Hagar and Ishmael away.

It’s interesting that at the moment Hagar fears that she and Ishmael will die, an angel appears and spares them (see Genesis 21:16-21). We’ll see why this is important when we turn to the story of Isaac’s sacrifice.

Abraham’s Only Son?

Genesis 22 opens with the words “Some time afterward, God put Abraham to the test” (Genesis 22:1). The author wants the reader to remember what just happened to Ishmael in Genesis 21. To make this point clear he refers to Isaac as Abraham’s “only” son (see verse 2). Abraham is being “put to the test.” He has to ask himself, “Is God the God of love? Is he true to his word? Did he save Ishmael as he promised he would? Will he spare Isaac so that my descendants will come forth from him as he promised?”

Abraham has faith, and he does as he is told. He takes Isaac to be sacrificed.

Wait! He does what!? Why would he willingly offer his son as a sacrifice? The author of Hebrews helps to shed some light on this. Hebrews recounts a litany of examples of Abraham’s faith, but two in particular stand out:

By faith he received power to generate, even though he was past the normal age … So it was that there came forth from one man, himself as good as dead, descendants as numerous as the stars in the sky and as countless as the sands on the seashore. (Hebrews 11:11-12)

By faith Abraham, when put to the test, offered up Isaac, and he who had received the promises was ready to offer his only son, of whom it was said, ‘Through Isaac descendants shall bear your name.’ He reasoned that God was able to raise even from the dead, and he received Isaac back as a symbol. (Hebrews 11:17-19).

God has proven himself to Abraham more than once. He knows that God is a God of love who is true to his word. Abraham at his advanced age was “as good as dead,” yet he bore children. Because of this he knows by faith that Ishmael is safe, just as he knows by faith that Isaac will be. Even if he can’t see how, he “reasoned that God was able to raise even from the dead.” just as he had brought forth life from a man as good as dead. And as Abraham is about to commit this deed, an angel spares Isaac just as an angel had spared Ishmael.

The Test Results Are In

Abraham has put God to the test more than once in his life. This was Abraham’s turn to be tested. Here he proves to himself what God already knew, that God is a God of love who is true to his word. We can, and should, entrust everything to him, including our life. He will never disappoint us in his generosity. Reading this story we should ask ourselves, “What are we holding back from God? Where in our lives do we fail to trust him? How can we prove to ourselves that God is always faithful to his word?”
