Was Eve present in Genesis 2 before the Fall?
No, Eve was not present in Genesis 2 before the Fall. The text indicates only Adam was on the scene; Eve was still in Adam. This pattern shows the Body of Christ as the complement of Christ, taken from Him.
Les explains that in Ephesians 1:23 the word "fullness" could also be translated "complement." The Body of Christ, of which believers are members, is the complement of Christ. To illustrate this, Les goes back to Genesis 2, to Adam and Eve before the Fall. At that point Eve isn't even on the scene—just Adam. Eve is still in Adam. So before the Fall, Eve was not yet present as a separate person; she was in Adam. This pictures the Church as the complement of Christ, drawn from Him.
