In reality, Abraham sacrificed Himself, for He brought heavenly teachings to the world and conferred heavenly food upon mankind.

As to the third meaning of sacrifice, it is this: If you plant a seed in the ground, a tree will become manifest from that seed. The seed sacrifices itself to the tree that will come from it. The seed is outwardly lost, destroyed; but the same seed which is sacrificed will be absorbed and embodied in the tree, its blossoms, fruit and branches. If the identity of that seed had not been sacrificed to the tree which became manifest from it, no branches, blossoms or fruits would have been forthcoming. Christ outwardly disappeared. His personal identity became hidden from the eyes, even as the identity of the seed disappeared; but the bounties, divine qualities and perfections of Christ became manifest in the Christian community which Christ founded through sacrificing Himself. When you look at the tree, you will realize that the perfections, blessings, properties and beauty of the seed have become manifest in the branches, twigs, blossoms and fruit; consequently, the seed has sacrificed itself to the tree. Had it not done so, the tree would not have come into existence. Christ, like unto the seed, sacrificed Himself for the tree of Christianity. Therefore, His perfections, bounties, favors, lights and graces became manifest in the Christian community, for the coming of which He sacrificed Himself.

As to the fourth significance of sacrifice: It is the principle that a reality sacrifices its own characteristics. Man must sever himself from the influences of the world of matter, from the world of nature and its laws; for the material world is the world of corruption and death. It is the world of evil and darkness, of animalism and ferocity, bloodthirstiness, ambition and avarice, of self-worship, egotism and passion; it is the world of nature. Man must strip himself of all these imperfections, must sacrifice these tendencies which are peculiar to the outer and material world of existence.

On the other hand, man must acquire heavenly qualities and attain divine attributes. He must become the image and likeness of God. He must seek the bounty of the eternal, become the manifestor of the love of God, the light of guidance, the tree of life and the depository of the bounties of God. That is to say, man must sacrifice
