Man, the carnal man, lives in darkness. All mankind has turned aside from the truth, the true light, and has gone to corruption. There is nothing wholesome about man, and nothing good in what he can do. Ever.
The Spiritual Man, however, as Paul described, has died to it. He has died to himself, to the world with all its desires, and has died to himself. The case is so edged that Paul states that he is crucified to the world and the world is crucified to himself (Galatians 6:14).
