The spirit is Saved Because Christ Lays Down His Life for me;

The soul is Saved Because I Deny myself and Follow the Lord.

The spirit is Saved on the Basis of Faith: once having Believed the matter is Forever Settled, never again to be shaken.

The soul is Saved on the Basis of Following: it is a Lifelong Matter, a Course to be Finished.

Only one who has had Enteral Life is able to Deny himself, Take Up the Cross, and Follow the Lord.

For a sinner who has not yet Possessed Eternal Life, what he needs to do is not to try to Follow the Lord but to Believe in the Lord.
