Adam and Eve died the day they ate
of the Tree of the Knowledge of Good and Evil.

          They died spiritually.
          They lost their knowledge of God.
          They lost their fellowship with God.

      The gained a knowledge of good and evil.

Physical death came as a result of their separation from God.

If Adam wanted to eat, he was going to have to till the soil by the sweat of his brow.

This is real death.

To live in a physical body, full of fear, constantly needing to justify themselves by the reasoning of their intellect.

Out of that comes emotional sickness
Out of emotional sickness comes physical sickness.
Out of physical sickness come physical death.

Adam and Eve after leaving the Garden of Eden;
           could no longer enjoy the fruit of the garden.
           could no longer enjoy the freedom of the garden.
