Genesis 22:1-13 - Some time later, God tested Abraham’s faith. “Abraham!” God called. “Yes,” he replied. “Here I am.” 2 “Take your son, your only son—yes, Isaac, whom you love so much—and go to the land of Moriah. Go and sacrifice him as a burnt offering on one of the mountains, which I will show you.” 3 The next morning Abraham got up early. He saddled his donkey and took two of his servants with him, along with his son, Isaac. Then he chopped wood for a fire for a burnt offering and set out for the place God had told him about. 4 On the third day of their journey, Abraham looked up and saw the place in the distance. 5 “Stay here with the donkey,” Abraham told the servants. “The boy and I will travel a little farther. We will worship there, and then we will come right back.” 6 So Abraham placed the wood for the burnt offering on Isaac’s shoulders, while he himself carried the fire and the knife. As the two of them walked on together, 7 Isaac turned to Abraham and said, “Father?” “Yes, my son?” Abraham replied. “We have the fire and the wood,” the boy said, “but where is the sheep for the burnt offering?” 8 “God will provide a sheep for the burnt offering, my son,” Abraham answered. And they both walked on together. 9 When they arrived at the place where God had told him to go, Abraham built an altar and arranged the wood on it. Then he tied his son, Isaac, and laid him on the altar on top of the wood. 10 And Abraham picked up the knife to kill his son as a sacrifice. 11 At that moment the angel of the Lord called to him from heaven, “Abraham! Abraham!” “Yes,” Abraham replied. “Here I am!” 12 “Don’t lay a hand on the boy!” the angel said. “Do not hurt him in any way, for now I know that you truly fear God. You have not withheld from me even your son, your only son.” 13 Then Abraham looked up and saw a ram caught by its horns in a thicket. So he took the ram and sacrificed it as a burnt offering in place of his son.
Abraham obeyed God. God is telling Abraham to sacrifice his son, to kill his son, the son whom he loves, the son of the promise. The supreme test for Abraham, after building that dreadful altar, after tying up his teenage son and laying him on the altar must have been that moment he raised the knife in his hand to plunge it into the heart of his son. Tradition says, the altar that Abraham built, to sacrifice his son, is located on the same spot, that 2,000 years later, would be named Mount Calvary - where God took his son, his only son, the son whom he loved, and tied him up, and laid him on a cross, and killed him. But the death of God’s son was a substitute, a substitute for us, and for Isaac, because Abraham passed the test, and Isaac was spared - so that Isaac could have a son, and that Isaac’s son could have a son, and so that through this descendancy the promises of the covenant would come to pass.
