Why does God command Abraham to offer Isaac after promising that Isaac would be the son through whom his descendants would come?

Abraham waited decades for the son God promised, and then God asks for him back on a mountain. The test hangs on whether Abraham will trust the promise when the command seems to cancel it, and the story answers on the far side of the knife.

After these things, God tested Abraham, and said to him, “Abraham!” He said, “Here I am.” He said, “Now take your son, your only son, Isaac, whom you love, and go into the land of Moriah. Offer him there as a burnt offering on one of the mountains which I will tell you of.” Abraham rose early in the morning, and saddled his donkey; and took two of his young men with him, and Isaac his son. He split the wood for the burnt offering, and rose up, and went to the place of which God had told him. On the third day Abraham lifted up his eyes, and saw the place far off. Abraham said to his young men, “Stay here with the donkey. The boy and I will go over there. We will worship, and come back to you.” Abraham took the wood of the burnt offering and laid it on Isaac his son. He took in his hand the fire and the knife. They both went together. Isaac spoke to Abraham his father, and said, “My father?” He said, “Here I am, my son.” He said, “Here is the fire and the wood, but where is the lamb for a burnt offering?” Abraham said, “God will provide himself the lamb for a burnt offering, my son.” So they both went together. They came to the place which God had told him of. Abraham built the altar there, and laid the wood in order, bound Isaac his son, and laid him on the altar, on the wood. Abraham stretched out his hand, and took the knife to kill his son. Yahweh’s angel called to him out of the sky, and said, “Abraham, Abraham!” He said, “Here I am.” He said, “Don’t lay your hand on the boy or do anything to him. For now I know that you fear God, since you have not withheld your son, your only son, from me.” Abraham lifted up his eyes, and looked, and saw that behind him was a ram caught in the thicket by his horns. Abraham went and took the ram, and offered him up for a burnt offering instead of his son. Abraham called the name of that place “Yahweh Will Provide”. As it is said to this day, “On Yahweh’s mountain, it will be provided.”

Genesis 22:1–14

Yahweh visited Sarah as he had said, and Yahweh did to Sarah as he had spoken. Sarah conceived, and bore Abraham a son in his old age, at the set time of which God had spoken to him. Abraham called his son who was born to him, whom Sarah bore to him, Isaac. Abraham circumcised his son, Isaac, when he was eight days old, as God had commanded him. Abraham was one hundred years old when his son, Isaac, was born to him. Sarah said, “God has made me laugh. Everyone who hears will laugh with me.” She said, “Who would have said to Abraham that Sarah would nurse children? For I have borne him a son in his old age.”

Genesis 21:1–7

By faith, Abraham, being tested, offered up Isaac. Yes, he who had gladly received the promises was offering up his only born son, to whom it was said, “Your offspring will be accounted as from Isaac,” concluding that God is able to raise up even from the dead. Figuratively speaking, he also did receive him back from the dead.

Hebrews 11:17–19

Against hope, Abraham in hope believed, to the end that he might become a father of many nations, according to that which had been spoken, “So will your offspring be.” Without being weakened in faith, he didn’t consider his own body, already having been worn out, (he being about a hundred years old), and the deadness of Sarah’s womb. Yet, looking to the promise of God, he didn’t waver through unbelief, but grew strong through faith, giving glory to God, and being fully assured that what he had promised, he was also able to perform.

Romans 4:18–21

What does Isaac's question about the lamb, and Abraham's answer, show about what Abraham expected on Mount Moriah?

Isaac carries the wood and asks where the lamb is. Abraham's answer straddles the test: he does not explain the plan, and he does not name a substitute he cannot yet see. The rest of the story turns on that answer.

Isaac spoke to Abraham his father, and said, “My father?” He said, “Here I am, my son.” He said, “Here is the fire and the wood, but where is the lamb for a burnt offering?” Abraham said, “God will provide himself the lamb for a burnt offering, my son.” So they both went together.

Genesis 22:7–8

Abraham lifted up his eyes, and looked, and saw that behind him was a ram caught in the thicket by his horns. Abraham went and took the ram, and offered him up for a burnt offering instead of his son. Abraham called the name of that place “Yahweh Will Provide”. As it is said to this day, “On Yahweh’s mountain, it will be provided.”

Genesis 22:13–14

Your father Abraham rejoiced to see my day. He saw it and was glad.”

John 8:56

Why does the king separate the nations as a shepherd divides sheep from goats, and what is he looking for in them?

The parable ends with the king judging nations on whether they fed, clothed and visited the lowest people they met. Both groups are surprised, which means the care was not done to be seen, and the question is about what that care to a neighbor has to do with a person's relation to the king.

“But when the Son of Man comes in his glory, and all the holy angels with him, then he will sit on the throne of his glory. Before him all the nations will be gathered, and he will separate them one from another, as a shepherd separates the sheep from the goats. He will set the sheep on his right hand, but the goats on the left. Then the King will tell those on his right hand, ‘Come, blessed of my Father, inherit the Kingdom prepared for you from the foundation of the world; for I was hungry and you gave me food to eat. I was thirsty and you gave me drink. I was a stranger and you took me in. I was naked and you clothed me. I was sick and you visited me. I was in prison and you came to me.’ “Then the righteous will answer him, saying, ‘Lord, when did we see you hungry and feed you, or thirsty and give you a drink? When did we see you as a stranger and take you in, or naked and clothe you? When did we see you sick or in prison and come to you?’ “The King will answer them, ‘Most certainly I tell you, because you did it to one of the least of these my brothers, you did it to me.’ Then he will say also to those on the left hand, ‘Depart from me, you cursed, into the eternal fire which is prepared for the devil and his angels; for I was hungry, and you didn’t give me food to eat; I was thirsty, and you gave me no drink; I was a stranger, and you didn’t take me in; naked, and you didn’t clothe me; sick, and in prison, and you didn’t visit me.’ “Then they will also answer, saying, ‘Lord, when did we see you hungry, or thirsty, or a stranger, or naked, or sick, or in prison, and didn’t help you?’ “Then he will answer them, saying, ‘Most certainly I tell you, because you didn’t do it to one of the least of these, you didn’t do it to me.’ These will go away into eternal punishment, but the righteous into eternal life.”

Matthew 25:31–46

“The King will answer them, ‘Most certainly I tell you, because you did it to one of the least of these my brothers, you did it to me.’

Matthew 25:40

What good is it, my brothers, if a man says he has faith, but has no works? Can faith save him? And if a brother or sister is naked and in lack of daily food, and one of you tells them, “Go in peace. Be warmed and filled;” yet you didn’t give them the things the body needs, what good is it? Even so faith, if it has no works, is dead in itself.

James 2:14–17

But whoever has the world’s goods and sees his brother in need, then closes his heart of compassion against him, how does God’s love remain in him? My little children, let’s not love in word only, or with the tongue only, but in deed and truth.

1 John 3:17–18
