@Eternally Grateful While up to a point I appreciate the Reformed writers, yet it is hard not to part company with them when they sometimes try to assert that the law (rather than the Gospel) is the rule of the believer's life (according to the 1689 Confession); an earlier Baptist confession does not say this; it's as if the Israel/church blending of Presbyterianism was inserted into the 1689 Baptist Confession.
Desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm.
The first error of those who don't know what they are talking about in teaching the law, is separating the law, word, doctrine, rule, and gospel of God from each other, as though someone can be obeying the gospel of Jesus, while transgressing the law of Christ.
The good news of Jesus is not being counted as righteous and spiritually uncondemned, while fornicating with the flesh.: the good news is to become spiritually pure and righteous altogether withing the cup, that we may not be found fornicating with the flesh.
For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature. And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God.
The the OT, the law of Moses was the law of God that judges every transgressor, which cut of males uncircumcised in flesh after the 8th day.
In the NT, it is the law of Christ that judges every transgressor, which no more includes circumcision of the flesh, but certainly cuts of them fornicating with the flesh.
The greater power of the law of Christ, than that of Moses, is to cut off them lusting with the heart to fornicate, before even doing so with the flesh.
Doers of the law of Christ are the doers of the word of Christ, and no man not doing His word, by transgressing His law is justified by Christ.
There is no loving Jesus Christ and having part in His gospel, while sinning with the devil against His word and law:
Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind.
Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
No unrighteous fornicator is inheriting the kingdom of God while fornicating.
The good news of Jesus Christ is not being saved and justified, while fornicating 'under grace', but is by grace having help not to be a lustful fornicator, and so be found condemned with all other lustful fornicators on earth:
But if, while we seek to be justified by Christ, we ourselves also are found sinners,
is therefore Christ the minister of sin? God forbid.
Paul needed continually remind newborn Christians, that being saved by grace through faith, and not by outward works of the law only, was not the gospel of being saved by grace through faith while transgressing the law outwardly.
Jesus comes first to His own, to purify the hearts of them doing His law outwardly only.
He then goes on to seek to save those not doing His law at all: outward transgressors aren't even in the running.
He first purifies His law-abiding body, then He adds to His body unsaved transgressors, if they repent of sinning against Him and His law.
