Hebrews 11:17

By faith Abraham, when he was tried, offered up Isaac; by the same excellent faith Abraham alone, and by himself considered, being tried by God, in a rare way, to give proof of the truth of his faith in and love to him above all, was to take his only son, his darling, and to offer him for a whole burnt offering on Mount Moriah, to himself, Genesis 22:2. Which command of God was not unjust, he having absolute sovereignty and dominion over all persons and their lives, having power to kill, and to make alive, Deuteronomy 32:39. This son of his he offered up as God commanded; for in his heart he had fully parted with him to God, and proceeded so far in execution, as, if God had not dispensed with it, it had been actually done, he would have killed him and burnt him to ashes on the altar, Genesis 22:3,Genesis 22:6. And he that had received the promises offered up his only begotten son: this mighty faith enabled him to do this, though he was his only begotten son by promise, and in the church's line, concerning whom he had received so many promises, and in whom only they were to be fulfilled, as that a numerous seed should descend from him, who should inherit Canaan, and through whom Christ was to descend into the world, in whom himself and all nations were to be blessed. Yet faith silenceth reason and natural affection, assureth him God could fulfil his promises by him though he should offer him, as he raised him from a dead body and womb at first, and gave him to him: so he obeyeth God's word, and offereth him.
