As a stand alone story, this is hard to comprehend. Abraham does not ask for an explanation. He just obeys. But in the context of Abraham’s life, this is just the latest in a series of messages God has given him. And he has tried second guessing God before. So it is not surprising that he tells Sarah nothing about how he is going to stay her son. He tells his 2 servants that went with them nothing. He tells Isaac nothing. He just holds fast to the promise that this son will produce many nation’s. He knows that in order for that to happen, God will have to raise Isaac from the dead.
And let us not forget Isaac. He had to let his father to him up and prepare him to be sacrificed. This prefigures Christ, who obediently went to the cross. Although it is not recorded, Isaac must have had his own Gethsemane moment, where he said, “If there is any other way,” before yielding to the father’s will.
What is also not recorded is the hilarious joy Abrahan and Isaac must have experienced when the Lord told Abraham to stop, and when they saw the ram. God had prepared a sacrifice all along! And now the father and his son worshipped as never before.
