Evangelicals believe that the context, particularly taking in the grammatical tense that Paul uses throughout Rom Ch 6, is helpful in determining what he is talking about.
It is true that quite often the WTS has used Ro 6:7 to justify its teaching that the incorrigible are given a "second chance" when they are resurrected sometime during the Millennium. They give the impression that Paul is saying that once one dies, the debt he owed has been paid so when resurrected that person can now start again, a free from the burden of his past.
Is that what Paul is referring to? Ever notice how, whenever the WTS uses this verse they never consult the context, ie the surrounding vss of Ch 6, to detirmine Paul's meaning.
The question that Paul is adressing is not the resurrection, but one that the WTS itself often uses, cynically, to negate the grace of God in forgiving us, thus no longer requiring us to "work" to expiate our sins. What? You mean that God has forgiven me all my sins? Even those I hav'nt even committed yet? Every single sin? And all I gotta to is believe on the Lord Jesus? Yes.
But that means I can just keep on sinning since I have already been fogiven, right?
Wrong. Shall we go on sinning, so that grace may increase? No. 6:1.
Why?
Because there are two kinds of people in the world today. Those who are dead and those who are alive. The thing that seperates them is sin. The awfullness of sin has never really been made plain to the R&F of the WTS. If you continue in your sins, then, being alive to sin, you are in fact dead to God. If you are dead to sin, then you are alive to God. This is the alternative Paul discusses in Ro ch 6.
Either be alive or dead. If belief in Christ is motivating you, then consider yourself alive. [6:11]. This will cause you to break the power of sin in your life, no longer obeying its desires. You cannot be, as the WTS suggests, alive to God, by going from d-t-d, yet at the same time also alive to sin.[6:16]
If you are alive to sin, then sin has a hold of you. No matter how many times you ask forgivness, no matter how many hours you spend in the field service, because you are alive to sin, you are unforgiven.
But what if you have died to sin? Ah! That, according to Paul, is precisely the point!! You are then acquitted from sin, and it has no hold on you [6:7] The grace of God has now got a hold of you, and you are alive to Him.[6:17]
Belief in Christ, living what Paul calls an existence "in Christ" causes two seperate conditions in the believers life: 1. Complete forgiveness, of all sin.Past. Present. And future [Note that according to the WTS, belief in the WTS only ensures forgiveness of something called "Adamic sin" your own personal sins need expiation by your efforts] 2: Being now acquitted from sin, you enjoy fellowship with Christ, for while yet being a sinner, capable of sin, you no longer are alive to it.[6:2]
If you wish to go from d-t-d, evangelize, visit hospitals, feed the poor, or whatever, you don't do so to get forgiveness for sin, because you are already acquitted from it, but because the appreciation for the grace of God motivates you.
The first guy to understand this point clearly was Martin Luther, back in the 16th century
And he broke from Rome.
Many ex-WT followers are in the same position, leading to their break from Brooklyn Heights.
