Christians enter the world spiritually dead in trespasses and sins, walking according to the course of this world and the prince of the power of the air, fulfilling the lusts of the flesh and mind, and by nature children of wrath. Through union with Christ, those whom God calls, baptizes, and gives His Holy Spirit are made alive together with Him. This union produces regeneration, a spiritual change in which the sinful nature is transformed and a new principle is implanted in the heart, enabling response to God in faith. The same power that raised Christ from the dead raises believers spiritually from the grave of sin. As a result they are no longer dead to God, no longer under condemnation or wrath, and no longer slaves of sin. They have died to sin through baptism into Christ's death and are therefore freed from its dominion and control, though sinful tendencies remain in the flesh. They are no longer in Adam but in Christ, reckoned dead indeed to sin yet alive to God. This change places them under grace rather than law in their relationship to God and leads them to walk in newness of life, governed by a renewed mind that desires righteousness, holiness, and fellowship with the Father. The process continues as they overcome remaining human nature, the world, and Satan, bearing fruit and growing in the character of God until the resurrection.

The Days of Unleavened Bread memorialize the truth that believers have died to sin through their union with Jesus Christ, and this death marks the beginning of a wholly new relationship to sin's power. Because unleavened bread represents the absence of sin, these days are not meant to be a time of dwelling on sin but of recognizing that its penalty has been removed and that Christ's righteousness has been ascribed to those who have been cleansed at Passover. Romans 6 provides the foundation for this understanding: those baptized into Christ Jesus were baptized into His death, buried with Him, so that just as He was raised from the dead, believers also walk in newness of life. The old man was crucified with Christ so that the body of sin might be destroyed and believers would no longer be slaves to sin, for "he who has died has been freed from sin." Because Christ died to sin once for all and now lives to God, believers are commanded to reckon themselves dead indeed to sin but alive to God in Christ Jesus. This death to sin is directly tied to liberty, the central theme of the season. Sin is depicted as a master whose slaves cannot escape except by dying or becoming the property of another; through spiritual death with Christ, the elect have passed from the dominion of sin into the service of righteousness. Paul insists that although believers are no longer under the penalty of the law, sin still must not be permitted to reign in the mortal body. Instead, believers present themselves to God as those alive from the dead, offering their members as instruments of righteousness rather than unrighteousness. Having been set free from sin, they have become slaves of God, bearing fruit to holiness with the end result of everlasting life. This dying to sin forms the first stage of a three-part process toward eternal liberty: Christ liberates from sin, the Holy Spirit enables obedient service to God under the law of liberty, and through that liberty believers produce righteous fruit reflecting God's own character—love, joy, peace, and the other attributes to be imitated. The law itself, pictured as a husband to whom one is bound until death, no longer holds authority once that death has occurred, freeing the believer to be joined to Christ. Likewise, the law functioned as a tutor bringing humanity to Christ so that justification by faith might be received. Because believers have died to sin, the Days of Unleavened Bread are not to be spent lamenting past transgressions but rather focused on the positive outworking of this freedom—loving and serving others, walking in newness of life, and glorifying God in body and spirit. Sin's penalty is past; its dominion has been broken. The proper response to having died to sin is not renewed bondage to selfish desire, but grateful, sanctified service to God, offering oneself as a living sacrifice, holy and acceptable, which is the reasonable outcome of having been delivered from sin's mastery through Christ's death and resurrection.

Being dead to sin forms the theological centerpiece of Paul's answer to the antinomian error that had infected the first-century church and that continues, in modified form, through dispensationalism and modern Christianity's separation of law and grace. Paul addresses this directly in Romans 6, a chapter that follows his earlier teaching on justification by faith and shifts the subject from a believer's legal standing before God to the believer's actual moral and spiritual condition after baptism—from justification to sanctification. The chapter opens with the pointed question of whether one may continue in sin so that grace may abound, and Paul's emphatic answer, "God forbid," is grounded in the reality that those baptized into Christ have been baptized into His death. Just as Christ died, was buried, and rose again, the believer's baptism symbolizes death to sin, burial in a watery grave, and resurrection to walk in newness of life. Paul explains that the old man is crucified with Christ so that the body of sin might be destroyed, "that henceforth we should not serve sin," for "he that is dead is freed from sin." This death to sin is not a one-time legal fiction but the basis for an ongoing manner of life: having died to sin and risen to new life, the believer is to live according to God's law rather than continuing in the old pattern of disobedience. Paul reinforces this by describing Christ as having died unto sin once and now living unto God, commanding believers to "reckon" themselves likewise dead indeed unto sin but alive unto God. The practical instruction that follows—"let not sin therefore reign in your mortal body"—is, in the Greek, a command to stop letting sin continue to rule, exposing that some in the church were treating grace as a license for ongoing sin, precisely the error Jude condemns as "turning the grace of our God into lasciviousness." Paul insists that being "not under the law, but under grace" does not remove the obligation to righteousness; rather, freedom from the law's condemning penalty obligates the believer all the more to become a servant of righteousness rather than a servant of sin, since the wages of continued sin is death. This teaching directly refutes dispensationalism's claim that grace and law are opposing principles belonging to separate eras, since Paul, writing in the same period as the false teachers Jude and John warned against, shows that dying to sin does not mean law is abolished but that the believer is freed to obey it from the heart. Being dead to sin thus connects to the larger purpose of demonstrating that no biblical warrant exists for permission to sin, and that true justification, symbolized in baptism's death and resurrection, must produce holiness of life and a living, faithful relationship with Christ rather than the confused, lawless doctrines that Gnosticism and its modern descendants promote.
