This episode goes deeper into the depth of spiritual death in which all mankind participates. Spiritual death does not simply refer to outward transgressions, but also describes the spiritual state of the inner man that produced them. Paul says in Colossians 2:13 that we were "dead in our trespasses AND the uncircumcision of our flesh," indicating that spiritual death is descriptive of both the acts themselves (dead works) and the one who is uncircumcised in the flesh. So when one repents of dead works, he also has a change of mind about the self that produced them characterized by death. The solution to spiritual deadness is the circumcision of Christ, the supernatural cutting away of the flesh in regeneration.
