The following excerpt from David B. Hart’s The Doors of the Sea properly ’sets the table’ for Christus Victor:
In the New Testament, our condition as fallen creatures is explicitly portrayed as a subjugation to the subsidiary and often mutinous authority of angelic and demonic “powers,” which are not able to defeat God’s transcendent and providential governance of all things, but which certainly are able to act against him within limits of cosmic time. This age is ruled by spiritual and terrestrial “Thrones, dominions, principalities, and powers” (Col. 1:16; cf. 1 Cor. 2:8; Eph. 1:21; 3:10), by “the elements (stoicheia) of the world” (Gal. 4:3), and by “the prince of the power of the air” (Eph. 2.2), who - while they cannot ultimately separate us from God’s love (Rom. 8:38) - nevertheless contend against us: “For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places” (Eph. 6:12). Hence John’s Gospel calls the devil “the prince of this world” (John 12:31; 14:30; 16:11), while 2 Corinthians calls him (somewhat shockingly) “the god of this world” (2 Cor. 4:4), and 1 John says that “The whole world lies in the power of the evil one” (1 John 5:19). The cosmos, then, is divided between two kingdoms, that of God and that of death. And while God must triumph, death remains mighty and terrible until the end - it remains, in fact, the “Last enemy that shall be destroyed” (1 Cor. 15:26).
