Genesis 22:5 - Coke's Commentary on the Holy Bible

I and the lad will go—and come again— These words are expressive of Abraham's faith, and full assurance, that he should return to them with Isaac restored from the dead, if God should permit him to offer him as a real sacrifice. For that he had such an assurance (says Dr. Chandler in his Vindication) is plain from Hebrews 11:17; Hebrews 11:40. Which account of Abraham's faith is founded on the nature and reason of the thing. For this was the only possible way he had to reconcile God's promise of giving him a numerous posterity by Isaac, with this command, to offer him for a burnt-offering; for if it implied a total destruction of Isaac's life, then God would have falsified his promise. Neither does the supposition of his having such an assurance, derogate in the least from the perfection of his obedience; for it was not an assurance founded upon any revelation from Heaven, nor did it amount to absolute certainty; but it was such a faith, or moral persuasion, as sprang from reasoning justly on the Divine perfections, and the full confidence he had in the promises and truth of God. Now this being the case, the horror of the action must have been greatly alleviated in the parent's eye; for though he understood the order from God to be a command from God to put his son to death, yet he firmly believed it was not to be a lasting death till the general resurrection, but a death which was to be immediately abolished and succeeded by a resurrection to a long and prosperous life upon earth: a resurrection which would have given the father a pleasure equal to the pain of having deprived his son of life, and have filled the breast of his son with a joy unspeakable and full of glory.
