“In this way they came to the place which God had told him and there Abraham built the altar and arranged the wood on it. He bound Isaac, his son, and set him on the altar on top of the wood. Then Abraham stretched forth his hand and took the knife to slaughter his son.”
It is at this point where the faith of Isaac comes to surface next to the faith of his father. There is no longer any doubt as to whether Isaac understands what is going on for he has likely seen his father make many such sacrifices of animals. Even still, Isaac allows his father to bind his hands and feet like one would bind an animal for the slaughter and then lay his bound body on the fire. There is also no question that if Isaac chose to resist, this teenager could have easily maneuvered around his centenarian father. Yet, Isaac chooses to submit to his father’s will and his obedience to his father here moves from an active obedience to a passive one, trusting the call of God upon his life.
How, in Isaac’s submission, we see an image of Christ. Being God, Christ could have chosen not to go to the cross — yet such a choice would have condemned us all. In love for us and in submission to his Father, Jesus chose to go to the cross and submit to the cruelty of the sacrifice that was laid out before him. Isaac gives us a picture of that submission in his own life though we rarely give Isaac the credit for being a man of faith.
Abraham, too, stands as a man of faith, trusting God to fulfill his promise even through resurrecting his son from the dead. There will be another son (Jesus) who will indeed do just that — die and be raised from the grave to glory. While the promise to Abraham was through Isaac, the one who the promise is ultimately guaranteed by is Christ Jesus, who indeed is the seed of the woman promised in Genesis 3:15 as well as being the seed of Abraham (Galatians 3:16). Abraham believed the promise would be fulfilled through Isaac even if God had to raise him from the dead; God made his promise fulfilled and consummated through Christ, His Son, by resurrecting him from the dead that our hope and life may be in Him. Isaac is a shadow for us of the Christ to come. Praise be to God that he has indeed come and given us life and life eternal.
