Abraham got married when he was approximately 40 years old, and from that point on he dreamt of having a child with his wife Sara. During 60 years, this patriarch pursued this ideal.
Six or seven years later, after the birth of Isaac, God asked him to give the child as a sacrifice.
The dream that cost him more than six decades to be realized was now being requested to be presented as a sacrifice.
Why did God ask Abraham to sacrifice?
What was more important to God: Abraham or the sacrifice of the boy?
Obviously, Abraham! He was being tested by God.
However, some questions arise: Didn't God know who Abraham was? Didn't He know that His servant would obey His request? So why did He test him?
God knew that Abraham would answer His request, He knew everything, just like He knows all things, but His intention was that Abraham's sacrifice remain registered in history as an example to be followed by all those who believe in Him. That's the reason!
He did this so that we would know the kind of faith that pleases Him, that moves His hand, that makes Him declare and move heaven and earth to realize our dreams.
The worth of a sacrifice is not in the boy placed on the altar, but in the obedience.
When Abraham placed his son on the altar and raised the knife to kill him, God revealed the kind of faith He wants to future generations, the kind of people He seeks to enter into a covenant with Him: people who do not measure efforts, sacrifices, and go beyond their limits to please Him, to obey His voice.
Therefore, the kind of sacrifice you place on the altar reveals the quality of the relationship you have with the Lord God.
There are no obligations, whatsoever, in your surrender, and no one, no matter who they are, has the right to give their opinion about your "Isaac". And if you have any doubts, then you should not give that sacrifice, because it shows uncertainty on your behalf.
