“God said, “Take your son – your only son, whom you love, Isaac – and go to the region of Moriah! Sacrifice him there as a burnt offering on one of the mountains which I will indicate to you.” (Genesis 21:2, NET) This request may have sounded strange to Abraham; nevertheless, he obeyed because he loved God more than he loved his own. Accordingly, Abraham took the necessary provisions and went to the place God told him to go.
“When they came to the place God told him about, Abraham built the altar there and arranged the wood on it. Next he tied up his son Isaac and placed him on the altar on top of the wood.” (Genesis 21:9, NET) Abraham then took his knife to slaughter his son. However, the Lord prevented Abraham from harming the boy Isaac. “Abraham looked up and saw behind him a ram caught in the bushes by its horns. So he went over and got the ram and offered it up as a burnt offering instead of his son.” (Genesis 22:13, NET)
The mount Moriah is on the east side of the ancient city of Salem, which later became Jerusalem. The location where Abraham was to sacrifice his son of the promise – Isaac is on the west side of the city, directly opposite the Mount Moriah. Later, King Solomon built the temple on Mount Moriah. When the earthly high priest entered the most holy in the temple, the residence of God’s hiding place, he would face the location where Abraham was to sacrifice his Son he loved. On the same site where the ram was sacrificed instead of Isaac, God offered His Son He loved, the Lamb of God, as a sacrifice for the sin of the rebellious humankind, because He loved more than His own. Moreover, as the ram was entangled in thorns with his head, so also the Lamb of God, with a crown of thorns on His head, was sacrificed for our sin.
Our God did not leave the rebellious humankind in darkness. Not only did God clearly state what He will do for sinners, but also He demonstrated it. The humankind never had, and it does not have today, an excuse for not believing God and His Lamb, the Son of the promise.
