Where's the missing page?

I read the story of God testing Abraham today (Genesis 22). You know, the one where God sent Abraham off to sacrifice his son, but just before he goes through with it God stops him and blesses him for being so faithful.

I gotta believe there's a page missing somewhere. I mean, here you have Abraham, his son and a couple of servants heading out into the wilderness. Abraham leaves the servants and goes with his son to build an altar and offer a sacrifice to God. Isaac astutely notices that they have everything they need for their act of "worship" (I love that) except the sheep.

I can picture the scene... Isaac is walking along side his father, carrying as many branches has his little arms will hold. Abraham clutches the flint and the blade as his hands begin to sweat. He takes long, deliberate strides, staring into the distance as he considers the deed at hand. Isaac is doing all he can to keep up.

They walk silently. Abraham asking, "Do you have it son? We're almost there. You're doing good." Isaac calls back, "Yes, Dad. I'm alright."

A few paces more. Reluctantly Isaac speaks up. "Dad?" "Yes, son." "We have everything we need for the sacrifice, but where's the sheep?" Abraham, mouth dry and heart sinking, replies, "God will provide one, don't you worry." He's proud of his son, both for his quiet obedience and his keen observation.

They come to the place where God directed them. Abraham gathers a few large stones, rolling them into place. Isaac follows suit with smaller rocks. The altar is completed and Isaac passes the wood to his father, still curious about the sheep.

At this point I realize, something is missing. Clearly a page was left out of the original manuscript, because what follows next is Isaac being tied up and placed on the altar. Where's the dialogue? Where's the explanation? Surely Abraham had to explain to his son what was going on. Surely he told him what God said--how God instructed him. What child would, without explanation, let his father bind him and prepare him for sacrifice? Something is missing from the text.

As a father to a son I want to know what Abraham said. How did he convince his son to be the sacrifice? What did he say?!?!

But God in his infinite wisdom left those details out. It's not for us to know. I could be that Abraham had raised such a faithful and obedient son that he didn't have to explain anything. That's what I like to think. And that's the most challenging part of this entire story.

How can I, like Abraham, raise such an obedient son that the only explanation required of me is, "It's the Father's will"?
