Although many Christians see that Satan damages man, few realize that through Adam's fall Satan injected himself into man and has been installed in man's fallen body as the law of sin and of death. First John 3:8 says, "The Son of God was manifested, that He might destroy the works of the devil." In this verse the works of the devil refer not only to his outward, objective works to tempt and damage man but also to his inward, subjective works, that is, his evil works within man as the law of sin and of death. Christ as the Son of God destroyed the works of the devil not only by condemning sin in the flesh but also by imparting Himself into the believers as the law of the Spirit of life. On the cross Christ destroyed Satan (Heb. 2:14). In resurrection Christ became the life-giving Spirit in order to be installed in us as the law of the Spirit of life so that He as this law may conquer the law of sin and of death. This thought is expressed by the last stanza of Hymns, #84, a hymn written by Charles Wesley:
Come, Desire of nations, come!
Fix in us Thy humble home:
Rise, the woman's conquering seed,
Bruise in us the serpent's head;
Adam's likeness now efface,
Stamp Thine image in its place:
Final Adam from above,
Reinstate us in Thy love.
In Genesis 3:15 Jehovah prophesied that Christ as the seed of the woman would bruise the head of the serpent on the cross. On the one hand, Christ's bruising the serpent's head took place on the cross objectively; on the other hand, it is being accomplished in us subjectively. The bruising of the serpent's head is an objective fact accomplished by Christ, yet we need a subjective experience of this fact. The work of Christ as the law of the Spirit of life in our spirit overcomes the serpent as the law of sin and of death in our flesh. As the law of life within us, Christ makes His home in us and reconstitutes us with Himself, thereby transforming us from Adam's likeness into His image (Eph. 3:17; 2 Cor. 3:18; Rom. 8:29).
