It is amazing how a scripture can be twisted interpreted when taken out of context.
*** Rbi8 Romans 6:7 *** 7 For he who has died has been acquitted from [his] sin.
*** it-1 599 Death *** And since physical death discharges one from any debts or obligations existing up to that time (Ro 6:7), a Christian’s being freed or liberated from sin (Ro 6:2, 11) and from the condemnation of the Mosaic Law (Ro 7:2-6) is also likened to death, such one having ‘died’ to his former situation and obligations. The one figuratively dying in such a way, of course, is still alive physically and is now free to follow Christ as a slave to righteousness.—Ro 6:18-20; Ga 5:1.
*** it-1 603 Declare Righteous *** The apostle Paul states that the person who dies is “acquitted [form of di·kai·o'o] from his sin,” having paid the penalty of death.—Ro 6:7, 23.
*** it-2 138 Judgment Day *** Basis for judgment. In describing what will take place on earth during the time of judgment, Revelation 20:12 says that the resurrected dead will then be “judged out of those things written in the scrolls according to their deeds.” Those resurrected will not be judged on the basis of the works done in their former life, because the rule at Romans 6:7 says: “He who has died has been acquitted from his sin.”
However, Jesus said that unwillingness to take note of his powerful works and repent or unresponsiveness to God’s message would make it hard for some to endure Judgment Day.—Mt 10:14, 15; 11:21-24.
*** it-2 788 Resurrection *** Time of the earthly resurrection. We note that this judgment is placed in the Bible in the account of events occurring during Christ’s Thousand Year Reign with his associate kings and priests. These, the apostle Paul said, “will judge the world.” (1Co 6:2) “The great and the small,” persons from all walks of life, will be there, to be judged impartially. They are “judged out of those things written in the scrolls” that will be opened then. This could not mean the record of their past lives nor a set of rules that judges them on the basis of their past lives. For since “the wages sin pays is death,” these by their death have received the wages of their sin in the past. (Ro 6:7, 23) Now they are resurrected that they might demonstrate their attitude toward God and whether they wish to take hold of the ransom sacrifice of Jesus Christ that was given for all. (Mt 20:28; Joh 3:16) Though their past sins are not accounted to them, they need the ransom to lift them up to perfection. They must make their minds over from their former way of life and thought in harmony with God’s will and regulations for the earth and its population. Accordingly, “the scrolls” evidently set forth the will and law of God for them during that Judgment Day, their faith and their obedience to these things being the basis for judgment and for writing their names indelibly, at last, into “the scroll of life.”
*** w97 5/15 7 Should You Believe in Reincarnation? *** Yes, man is to blame for much of his misery. Since the soul is not immortal, however, the law of ‘reaping what you sow’ cannot be used to connect human suffering to a karma—deeds of a supposed previous life. “He who has died has been acquitted from his sin,” states the Bible. (Romans 6:7, 23) Thus the fruitage of sin is not carried over to a life after death.
*** w95 11/15 19 Stay in the "City of Refuge" and Live! *** 17 Must those resurrected during Jesus’ Thousand Year Reign enter the antitypical city of refuge and remain there until the death of the high priest? No, because by dying they paid the penalty for their sinfulness. (Romans 6:7; Hebrews 9:27) Nevertheless, the High Priest will help them to reach perfection. If they successfully pass the final test after the Millennium, God will also declare them righteous with a guarantee of eternal life on earth. Of course, failure to comply with God’s requirements will bring condemnatory judgment and destruction upon any humans who do not pass the final test as integrity keepers.
*** w82 5/15 8-9 What Will Judgment Day Be Like? *** Contrary to popular opinion, Christ will not judge those who are resurrected on the basis of their past sins, many of which may have been committed in ignorance. The Bible explains that at death a person is set free or released from any sins he committed. It says: “He who has died has been acquitted from his sin.” (Romans 6:7) This means that when a person is resurrected he will be judged according to what he does during Judgment Day, not on the basis of what he did before he was resurrected.
Now, let's examine it within the context of the passage and Romans 6:7 takes on an entirely different meaning that even the celebrated WT scholars can not deny:
*** Rbi8 Romans 6:1-7 *** 6 Consequently, what shall we say? Shall we continue in sin, that undeserved kindness may abound? 2 Never may that happen! Seeing that we died with reference to sin, how shall we keep on living any longer in it? 3 Or do You not know that all of us who were baptized into Christ Jesus were baptized into his death? 4 Therefore we were buried with him through our baptism into his death, in order that, just as Christ was raised up from the dead through the glory of the Father, we also should likewise walk in a newness of life. 5 For if we have become united with him in the likeness of his death, we shall certainly also be [united with him in the likeness] of his resurrection; 6 because we know that our old personality was impaled with [him], that our sinful body might be made inactive, that we should no longer go on being slaves to sin. 7 For he who has died has been acquitted from [his] sin.
8 Moreover, if we have died with Christ, we believe that we shall also live with him. 9 For we know that Christ, now that he has been raised up from the dead, dies no more; death is master over him no more. 10 For [the death] that he died, he died with reference to sin once for all time; but [the life] that he lives, he lives with reference to God. 11 Likewise also YOU : reckon yourselves to be dead indeed with reference to sin but living with reference to God by Christ Jesus.
12 Therefore do not let sin continue to rule as king in YOUR mortal bodies that YOU should obey their desires. 13 Neither go on presenting YOUR members to sin as weapons of unrighteousness, but present yourselves to God as those alive from the dead, also YOUR members to God as weapons of righteousness. 14 For sin must not be master over You , seeing that You are not under law but under undeserved kindness.
Romans 6:1-14 (HCSB)
1 What should we say then? Should we continue in sin in order that grace may multiply?
2 Absolutely not! How can we who died to sin still live in it?
3 Or are you unaware that all of us who were baptized into Christ Jesus were baptized into His death?
4 Therefore we were buried with Him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, so we too may walk in a new way of life.
5 For if we have been joined with Him in the likeness of His death, we will certainly also be in the likeness of His resurrection.
6 For we know that our old self was crucified with Him in order that sin’s dominion over the body may be abolished, so that we may no longer be enslaved to sin, 7 since a person who has died is freed from sin’s claims.
8 Now if we died with Christ, we believe that we will also live with Him, 9 because we know that Christ, having been raised from the dead, no longer dies. Death no longer rules over Him.
10 For in that He died, He died to sin once for all; but in that He lives, He lives to God.
11 So, you too consider yourselves dead to sin, but alive to God in Christ Jesus.
12 Therefore do not let sin reign in your mortal body, so that you obey its desires.
13 And do not offer any parts of it to sin as weapons for unrighteousness. But as those who are alive from the dead, offer yourselves to God, and all the parts of yourselves to God as weapons for righteousness.
14 For sin will not rule over you, because you are not under law but under grace.
