Was the story of Abraham offering Isaac a preview of the New Testament?
Yes. The context states that many Old Testament events were just a preview of what took place in the New Testament, specifically as Abraham laid Isaac upon the altar. Isaac did not struggle or fight back but in complete obedience allowed Abraham to lay him upon that altar, prefiguring the Lord Jesus, who was obedient unto that kind of death.
Les explains that in the verses under consideration, God did not spare His Son but gave Him up to be crucified, mishandled, and misused by the powers then in vogue. He connects this to Isaac of old, teaching that many Old Testament things were just a preview of what took place in the New, as Abraham laid Isaac upon the altar. Les notes that Scripture gives no indication Isaac struggled, fought back, or tried to lay Abraham low. Instead, in complete obedience, Isaac let Abraham lay him upon that altar, just as the Lord Jesus was obedient unto that kind of death, as seen in Philippians.
And 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.
How do Old Testament events like Isaac's offering relate to the New Testament?
Old Testament events such as Isaac’s offering were previews of what took place in the New. As Abraham laid Isaac on the altar and Isaac obeyed without struggling, so God did not spare His Son but gave Him up to be crucified, and Jesus was obedient unto that kind of death.
Did Isaac struggle or fight back when Abraham laid him on the altar?
No. Scripture gives no indication that Isaac struggled or fought back when Abraham laid him on the altar. Instead, in complete obedience, he allowed Abraham to lay him upon that altar. This foreshadows Christ's own obedience unto death, as the Old Testament previewed what took place in the New.
