Just to be clear, the test that Avraham passed at the Akeidah is that he stopped shechting his child.
Up until that point in time child sacrifice was a normal part of religious culture in religions throughout the world. When Avraham was confronted with that test, he was willing to obey. Perhaps reluctantly, but he obeyed.
One question is why he did not protest the sacrifice of his son in the way that he protested for Sodom. One answer is because child sacrifice at that time was the accepted convention of obeying and demonstrating faith in your God. Of course you're not going to object to that highest calling.
But God had other plans for the world and God was testing Abraham to see if he would be his willing vessel:
Abraham bind your son.
Yes God.
Abraham sacrifice your son.
Yes God.
Abraham, stop.
God, I'm ready to do this for you.
Abraham, stop.
Oh, you really want to stop?
Abraham, we're not doing this anymore, I am holding back your hand from this.
I understand God. Let this be a lesson to all... You do not want us do this kind of activity.
Very good Abraham. We are changing the world. But if you feel the need, here is a ram. But no more humans.
Baruch Hashem.
We are changing the world.
Likewise, let this be a lesson to us today as well. God wants us to demonstrate to the world a more ethical and moral standard that others may follow.
