Genesis 22 is a fairly well-known story of Abraham’s faith in God being confirmed by his willingness to sacrifice his son, Isaac. Of course, God does not desire human sacrifice, so He provides a ram for Abraham to offer instead of his son. The moral of the story is obviously a willingness to be obedient to God, to put your trust in Him, even when it seems dangerous or absurd.
Many commentators correctly see a link between this story of Genesis 22 and the crucifixion of Jesus. God, like Abraham, was willing to offer up His Son for the salvation of the world. The legitimate question comes up: why would God do such a thing? Isn’t it cruel to sacrifice your son? And, by the way, isn’t it the son who suffers more than the father. The answer to these questions requires a contextual reading of the text.
In the ancient world, and perhaps most so in the Semitic world, the role of the firstborn son cannot be understated. Anyone who has spent time around people of Middle Eastern descent notices the great honor granted the firstborn son of the family. In the case of Isaac, although he was not what we Americans would classify as the firstborn to Abraham, for family purposes in the ancient Near East, Isaac was the firstborn, the only-begotten of Abraham from his wife, Sarah, and the heir to Abraham’s inheritance. Not only was the firstborn the heir, but the thinking in this time was that the firstborn especially (although, technically, not exclusively) continues the life of the parents. In other words, your life continues to exist through your progeny. To have no children, or for your children to die before re-producing, means your name and life is cut off for eternity (at this time, there was little or no idea like we have of life after death).
In this way of thinking, to allow your firstborn, only-begotten son to die means to essentially kill yourself. You are allowing your name, your inheritance, to die. You are being cut off the earth. You are making the sacrifice. So in Genesis 22, Abraham is himself making a great sacrifice. He spent 100 years childless, with no one to carry on the family name. Finally, God intervened and gave him a child, and now God asks Abraham to offer the child as a sacrifice. This would again put Abraham in the position of dying off with no inheritance, no name, no memory of him left on earth. Despite this, Abraham puts his trust in God, realizing the son he was given is not his own, but a gift from God. Abraham understands he is accountable to God for the child, and so obeys God’s seemingly outlandish command. Abraham is then rewarded and reinforced for his obedience and God reveals this scenario as a simple test of Abraham’s faith.
Incidentally, this way of thinking is also significant in the New Testament. That Jesus is underscored as God’s firstborn, only-begotten Son, dramatizes even more the crucifixion of Jesus. Before the victorious resurrection, it is as though God’s name, His inheritance, and the memory of Him is completely obliterated from the face of the earth.
