The awakened will within a person prepares to surrender its own dearest product, and the whole scene is an inner act of offering rather than a killing. Abraham is the faith-nature, the part of the self that trusts the higher voice and follows it, and Isaac his son is joy, the laughter and delight that faith has brought forth, since the name itself opens as laughter. Building the altar and setting the wood in order is the deliberate arranging of the inner ground on which something is to be given up.
Binding the laughter and laying it on the wood is the moment a person offers even their own happiness to the higher self, holding nothing back. The wood, the dead matter of the tree, is the flesh made ready to bear the offering. What is pictured is the will placing its most treasured feeling on the altar of the body, willing to release the thing it loves most.

Wood: the dead matter of the tree, the flesh laid in order to bear the offering
Isaac: joy and laughter, the delight that faith brings forth, now bound and laid down
