Here is a brief summary of my argument in a lengthy exchange with a few friends on facebook.
First, God is all wise. Wisdom and knowledge come from him.
Second, this knowledge is dispensed in creation. Adam may have had the germ of knowledge at his creation, at the naming of animals, etc., but he lacked the true knowledge intended for every adopted Son of God.
Third, as Peter Leithart observes: ”
It was “not good” for Adam to be alone. But he wasn’t alone. He was alone with God. But God judged that “alone with God” was “not good.” Adam’s state became fully good only when another person joined him.
Truly, knowledge and completeness did not come until Adam was joined by another “likeness.” Another image-bearer is necessary, so that knowledge and a true humanity can function.
Fourth, this knowledge is grounded in the community of God. The God who is Three and One is not satisfied with isolation.
Finally, creation is the starting point of knowledge. To assume knowledge existed prior to the creation of woman is to imply knowledge can exist separated from other image-bearers. It is to make knowledge independent of response.
