Man; New
The Old Man and the Need for Renewal
Before the new man can be understood, the old man must be recognized. Paul uses the term "old man" (or "old self") to describe human nature as corrupted by sin — the entire pattern of thinking, desiring, and acting that characterizes life apart from God. Romans 6:6 declares that "our old self was crucified with him in order that the body of sin might be brought to nothing." Ephesians 4:22 urges believers to "put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires."
This old nature is not simply a matter of bad habits but a fundamental orientation of the whole person toward self-centeredness and rebellion against God. Colossians 3:9 connects the old self with practices like lying, anger, malice, and obscene speech. The old man is incapable of self-reform; what is needed is not improvement but transformation — a new creation altogether.
Becoming a New Creation in Christ
The new man comes into existence through regeneration, the supernatural work of the Holy Spirit that gives spiritual life to those who were dead in sin. Jesus explained this to Nicodemus: "Unless one is born again he cannot see the kingdom of God" (John 3:3). Paul states the reality with startling directness: "If anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come" (2 Corinthians 5:17).
This new creation is not a mere repair of the old but something genuinely new. Ephesians 4:24 describes putting on "the new self, created after the likeness of God in true righteousness and holiness." Colossians 3:10 adds that the new self is "being renewed in knowledge after the image of its creator." The language of creation echoes Genesis: just as God originally made humanity in His image, He now remakes believers in the image of Christ.
The Inward Man and Spiritual Transformation
Paul uses the term "inner man" or "inward man" to describe the center of the renewed person where the Holy Spirit operates. Second Corinthians 4:16 declares, "Though our outer self is wasting away, our inner self is being renewed day by day." Romans 7:22 speaks of delighting "in the law of God, in my inner being." Ephesians 3:16 prays that believers would be "strengthened with power through his Spirit in your inner being."
This inner transformation is not superficial but reaches the deepest springs of human motivation and desire. Grace operates from the center outward, not from the outside in. The result is not merely behavioral change but a fundamental reorientation of the heart, mind, and will toward God and His purposes.
The Spiritual Man versus the Natural Man
Paul draws a further distinction between the "natural man" and the "spiritual man" to clarify the nature of the new creation. The natural man — the person operating solely on human wisdom and ability — "does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned" (1 Corinthians 2:14). The "carnal" or "fleshly" man represents human nature dominated by appetites and self-interest (1 Corinthians 3:1-3).
By contrast, the spiritual man is human nature seized, permeated, and directed by the Holy Spirit. The word "spiritual" in its biblical usage does not mean ethereal or abstract but rather Spirit-directed. The spiritual person judges all things rightly (1 Corinthians 2:15), walks according to the Spirit rather than the flesh (Romans 8:4), and bears the fruit of the Spirit: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control (Galatians 5:22-23).
Living as the New Man
The New Testament presents the new man not as a finished product but as an ongoing reality that requires active participation. The commands to "put off" the old self and "put on" the new self (Ephesians 4:22-24; Colossians 3:9-14) indicate that believers must continuously align their daily lives with the new identity they have received in Christ. This is not earning salvation but living out its implications.
The new man also has a corporate dimension. Ephesians 2:15 declares that Christ's purpose was to create "in himself one new man" from Jew and Gentile, making peace between them. The new humanity in Christ transcends all the divisions that characterized the old: "Here there is not Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free; but Christ is all, and in all" (Colossians 3:11). The individual transformation of becoming a new person is inseparable from incorporation into a new community.
Biblical Context
The concept of the new man is primarily Pauline, appearing in Romans 6-8, 1 Corinthians 2-3, 2 Corinthians 4-5, Ephesians 2-4, Colossians 3, and Galatians 5-6. Jesus introduces the foundational concept through His teaching on being born again (John 3:1-8). The contrasts between old and new, outward and inward, natural and spiritual, carnal and Spirit-led form an interconnected web of teaching about the transformed life available through faith in Christ.
Theological Significance
The doctrine of the new man addresses the deepest human problem: not just what people do, but what they are. It teaches that salvation involves not merely forgiveness but transformation — a new creation with a new nature, new desires, and new capacity to know and serve God. The new man doctrine also has profound implications for Christian community, as the new humanity in Christ breaks down barriers of ethnicity, social status, and culture. It grounds Christian ethics in identity rather than mere obligation: believers act rightly because they are new people, not merely because they follow rules.
Historical Background
Paul's language of old and new man draws on both Jewish concepts of the two ages (this present evil age and the age to come) and the broader Hellenistic understanding of inner transformation. The Jewish expectation of a renewed humanity in the messianic age provides the background for Paul's claim that this renewal has already begun in Christ. Early church fathers such as Irenaeus and Athanasius developed the theme of recapitulation — Christ as the new Adam who restores what the first Adam lost. The Reformation emphasized that the new man is a gift of grace received by faith, not a human achievement.
