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.
“Loving God completely: the standard for good works”
This introductory episode defines good works as those that fulfill the great commandments, loving God and loving neighbor. Since all mankind since the fall is incapable of fulfilling these commandments, no "good" work is even possible. The episode answers one objection raised by many that unbelievers can do good works. While works toward neighbor might be outwardly "good," if actions do not have fulfillment of the great commandment as their objective, then so-called "good" works miss the mark. "Good" means little without reference to God, so unbelievers cannot do good works. Repentance from dead works refers to the changing of the mind about one's own sin and abilities to perform good works. Coupled with faith in Christ, salvation is the result.
