Why did God tell Abraham to sacrifice Isaac?

In short

Genesis calls it a test (22:1). God stopped Abraham, provided a ram, and Isaac lived. The story shows Abraham trusting that God would keep his promise through Isaac, and it shows that Israel’s God does not want child sacrifice. Christians also see it pointing ahead to God giving his own Son.

The Objection

A good God would not command a father to kill his son, even as a test. Abraham did not know he would be stopped, so the terror was real for him and for Isaac. Praising his readiness seems to teach that faith means doing something monstrous if God commands it, a lesson that has been used to excuse religious violence. Kant argued that Abraham should have doubted that such a voice could be God’s.

Put as its strongest advocates would put it.

The Christian Case

Scripture
The narrator tells the reader from the first verse that this is a test. The story ends with God stopping Abraham’s hand, providing a ram instead, and Abraham naming the place “The LORD will provide”. The climax is God’s provision, not a death.
Scripture
Isaac was the son through whom God had promised Abraham descendants. Abraham tells his servants “we will come again to you” and tells Isaac “God will provide himself a lamb”. Hebrews says he reasoned that God could raise Isaac from the dead. The test was whether he trusted the God who made the promise.
Historical evidence
Child sacrifice was practised among some of Israel’s neighbours. The Bible records a Moabite king doing it, and Israel’s law and prophets condemn it outright. Jeremiah says God never commanded it, “neither came it into my heart.” Many interpreters read Genesis 22 as showing that Israel’s God, unlike other gods, does not want children killed.
Scripture
Christians see the story as a picture of the gospel. Abraham is told to offer his “only son… whom thou lovest” on Moriah, the later site of the temple, and Isaac carries the wood. Paul writes that God “spared not his own Son”. Where Abraham was spared, God himself gave.
Historical evidence
Jews call this story the Akedah, “the binding”, and read it at Rosh Hashanah. Muslims also honour it. Qur’an 37:99–113 tells of a son who accepts the command and is ransomed “with a great sacrifice”. The Qur’an does not name him, and most Muslims understand him to be Ishmael. Eid al-Adha remembers this event.
Christians differ
Christians differ on how to handle the moral weight. Some stress that God, as giver of life, never intended the death to happen. Others stress that Abraham trusted God would raise or spare Isaac. Others, following Kierkegaard, see a real and troubling demand that faith cannot fully explain. Many combine these views.

Where the Evidence Is Weaker

The text does not say what Abraham felt or why God chose this particular test, and “now I know” (22:12) is hard to explain. The idea that the story is aimed against child sacrifice is an inference; Genesis does not say so. Hebrews’ account of Abraham’s reasoning was written many centuries later. Calling it “only a test” does not remove the difficulty, because Abraham did not know how it would end.

Arguments to Avoid

Using the story to suggest anyone today should obey a voice telling them to harm someone, when Scripture itself forbids child sacrifice.
Stating confidently that Isaac was a small child or a grown man, when Genesis does not give his age.
Treating the Muslim view that the son was Ishmael as an attack on the Bible, or mocking it.
Pretending the passage is easy or that Abraham felt nothing, since the moral difficulty is real and worth facing honestly.

Genesis 22:1–19

¹And it came to pass after these things, that God did tempt Abraham, and said unto him, Abraham: and he said, Behold, here I am. ²And he said, Take now thy son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt offering upon one of the mountains which I will tell thee of. ³And Abraham rose up early in the morning, and saddled his ass, and took two of his young men with him, and Isaac his son, and clave the wood for the burnt offering, and rose up, and went unto the place of which God had told him. ⁴Then on the third day Abraham lifted up his eyes, and saw the place afar off. ⁵And Abraham said unto his young men, Abide ye here with the ass; and I and the lad will go yonder and worship, and come again to you. ⁶And Abraham took the wood of the burnt offering, and laid it upon Isaac his son; and he took the fire in his hand, and a knife; and they went both of them together. ⁷And Isaac spake unto Abraham his father, and said, My father: and he said, Here am I, my son. And he said, Behold the fire and the wood: but where is the lamb for a burnt offering? ⁸And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together. ⁹And they came to the place which God had told him of; and Abraham built an altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar upon the wood. ¹⁰And Abraham stretched forth his hand, and took the knife to slay his son. ¹¹And the angel of the LORD called unto him out of heaven, and said, Abraham, Abraham: and he said, Here am I. ¹²And he said, Lay not thine hand upon the lad, neither do thou any thing unto him: for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from me. ¹³And Abraham lifted up his eyes, and looked, and behold behind him a ram caught in a thicket by his horns: and Abraham went and took the ram, and offered him up for a burnt offering in the stead of his son. ¹⁴And Abraham called the name of that place Jehovah-jireh: as it is said to this day, In the mount of the LORD it shall be seen. ¹⁵And the angel of the LORD called unto Abraham out of heaven the second time, ¹⁶And said, By myself have I sworn, saith the LORD, for because thou hast done this thing, and hast not withheld thy son, thine only son: ¹⁷That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies; ¹⁸And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice. ¹⁹So Abraham returned unto his young men, and they rose up and went together to Beer-sheba; and Abraham dwelt at Beer-sheba.

Hebrews 11:17–19

¹⁷By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son, ¹⁸Of whom it was said, That in Isaac shall thy seed be called: ¹⁹Accounting that God was able to raise him up, even from the dead; from whence also he received him in a figure.
