No, God did not tell Abraham to kill his son and here is why:

1. God told Abraham his son would have children.
2. Abraham’s son had no children.
3. Therefore, Abraham’s son was going to have children in the future.
4. Abraham knew that his son was going to have children in the future.
5. A person cannot have children if they are dead.
6. Therefore, Abraham’s son was going to be alive in the future.
7. Abraham knew that his son was going to be alive in the future.
8. Now, “to kill” means “to permanently remove a person from this life.”
9. Then, God said:

…[t]ake [your] son…and offer him…[as] a burnt offering….

10. Now, here is what God meant and what Abraham knew that God meant:
    

    INTERRUPT your son’s life, NOT permanently remove your son from this life, NOT kill your son.
