The sin of Adam and Eve in Eden, by which innocence was forever lost. Man became a sinner with a knowledge of good and evil, and a conscience; at the same time he got an evil nature which is enmity against God. In Christ we do not get the state of innocence restored, that is, we do not lose our knowledge of good and evil, but we are created anew in righteousness and true holiness (Eph. 4) which is a higher state.
