Torah Reading day 2 Rosh Hashana

So as we all know, Hashem commanded Avraham to send up his child as a sacrifice. After praying so hard to have a child Avraham is told to give him up and he's happy to do it to serve Hashem.

But what was the purpose of the test? For Hashem to see what Abraham is going to do? That doesn't make sense. 

Hashem tested Avraham like this so that Avraham can grow from it. He wants him to realize what he can do. As a result of Hashem's test, Avraham was able to perform an action which he didn't know he was capable of. 

The word נסיון can either be translated as test or miracle. 

If a miracle takes place, it shows us that Hashem exists. By seeing these things we realize what we can and should do. Avraham is now held up because it shows us an example of בתחון ואמונה with Hashem. So Hashem tested or held up Avraham as a banner to show us how to serve Him. 

On Rosh Hashana we should feel ready willing and able to accept Hashem in as king and in a sense sacrifice ourselves.
