Questions about Abraham and Isaac

Why was Isaac called “laughter”?
Isaac’s birth was something of a cosmic joke. Humor is often seeing something one might expect in one context in a context that you wouldn’t expect it. So the birth of a baby is wonderful and expected, but a birth to a ninety year old is unexpected and, frankly, funny. So everyone, when they heard of it, laughed at the absurdity of it. So they named him “laughter”—which is what Isaac means—so everyone could enjoy God’s cosmic joke.

Why did God tell Abraham to be rid of Hagar and Ishmael?
To send his slave and son into the desert with only a little food and water was against everything that Abraham stood for. But he did so because God himself said that He would protect them. If it weren’t for that promise, Abraham wouldn’t have done it. God told Abraham to do this, because He didn’t want there to be any question as to who would be in the inheritor of Abraham’s promise—it was only Isaac, no one else. Because only Isaac was the one whom God provided, so he could be the only real choice.

Why did God tell Abraham to kill his own son?
It says in the text that God was testing Abraham—he was seeing if Abraham truly loved God as much as he used to. God already knew the answer, but he was proving it to others, even as God proved to Satan that Job was truly righteous (see Job 1 and 2). It was important, for God was placing the entire salvation of the human race into Abraham’s hands. So God was occasionally testing his people to see where they stood with Him.

Why did God repeat Isaac’s name so often?
God repeated Isaac’s name for clarity, and also because what he was saying was so difficult. It is almost as if God was having a hard time making this request. God was expressing his own love for Isaac, even as he was talking about Abraham’s love for his son.

Does God approve of human sacrifice?
Absolutely not. God rejects human sacrifice again and again in the Scriptures, and condemns those who do it (Leviticus 18:21; Jeremiah 32:35; Exodus 13:13-15). Never has God approved of murder, and he has destroyed many civilizations who approve of it.

Isn’t it wrong for God to tempt Abraham to do evil?
This is kind of complicated. Even though it is wrong before God, there are occasions that God commands his people to do what is wrong before Him. And there are times that people do what is evil before God, but they are approved of despite it (See Judges 11). This is because people are so confused about what is right and wrong—even Abraham—that God often has to focus on people’s motivations rather than their actions. In other words, Abraham was willing to kill Isaac, because of his love of God. Others were willing to do other evil things, because of their care. In the same way, people today are willing to kill others in war, even though it is evil, but their motivations are pure. Does this make the action right? Not exactly. It means their motives are pure. But Jesus leads us not only to right motives, but right actions. He tells us exactly what God wants of us, while the rest of the Bible or humanity might be fuzzy or difficult to understand.

Did God tempt Abraham to evil? Not according to Abraham. And God didn’t allow him to do it anyway—he couldn’t allow his servant to do such evil. God knew that if Abraham loved him enough to obey him in this difficult thing, then he would obey in not doing the difficult thing. Morally, this is difficult to understand. But we must accept that God is pure and holy in all his ways, even if we don’t understand.

Why did Abraham agree to give up on what he was promised?
The book of Hebrews said that Abraham was willing because he believed that God would raise Isaac up from the dead (Heb. 11:19, above). Whatever the case, Abraham had waited 25 years for a son and he knew that God wouldn’t forsake his promise, no matter how difficult the circumstance looked. Abraham’s sacrifice is true, ultimate faith in God.
