Believers are not to live as unbelievers live. The new creation in Christ that we now are should bear no resemblance to the old self in Adam we once were. There should be, indeed there must be, a difference in conduct between redeemed and reprobate. Outside of Christ, we’re still in Adam, clothed with Adam, and still ruled by the sin of Adam. But those in Christ have been re-clothed in the robes of Christ’s righteousness. Paul commands us, therefore, to take off our Adam clothes—with all its corrupt and deceitful desires—and instead put on Christ’s robes that we might walk in true righteousness and holiness, in keeping with our new, redeemed natures.
