I can honestly say that no Christian I know has ever boasted or attempted to Justify to me a sin they have becoming ensnared in.
Then why do some preach it without shame in the name of Paul?
It's for certain there is no hint of shame with Paul, when proclaiming his own chief example. Indeed, he is glorifying the Lord for it beforehand and afterward.
The only shame he shows, is when he acknowledges his
past chief wickedness,
before he was saved and called by Jesus Christ.
Which chiefest of sinning was as Saul of Tarsus in the past, before he became Paul the apostle.
2Co 11:10
As the truth of Christ is in me, no man shall stop me of this boasting in the regions of Achaia.
Paul was boasting of his love for the brethren by not being burdensome to them. Does he also boast of His love for Christ by being a chiefest of sinner with Him? God forbid.
Such unashamed accusers of Paul, likewise trumpet him as a great example of lifelone double heartedness.
And they show no hint of shame nor wretchedness while doing so. Indeed, they never even speak of it being wretched, much less any need to be delivered from it.
They gladly magnify the middle of Romans 7, as some way to serve Christ in the mind alone, while serving sin with the flesh.
But do they acknowledge Paul also was speaking of the past, as opposed to his present godliness in the first verses? No.
And they certainly never keep teaching Romans y at the very last, where such doublemindedness with Christ is wretched and in need of deliverance, before moving on to the blessed walk in the Spirit of Romans 8.
To person they have all expressed shame & remorse, repentance and turning away from it.
This is the godly sorrow of the saint in Christ that repents, if we sin. This is not the pretence of sorrow for the sinners, who know they will continue sinning and repent not.
Did not Esau cry a lot about his own disobedience, yet repented not.
Who knows they will continue sinning, but them that believe and preach they will? How long before their own godly sorrow, becomes sorry lip service?
2 Cor 7:10
For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.
Could be due to the fact that anyone who knows me knows that attempting to boast or justify sin will not get a favorable response form me.
What we preach, we justify, whether doing good or evil.
If we preach continued sinning, we justify it in life. If we preach doing righteousness, we are justified by it in life.
Who preaches continued sinning, but them that declare they certainl will continue sinning, and justify it by declaring it is impossible to sin not?
Who is a preacher of righteousness and justification by righteousness, but them that declare we must cease sinning in Christ, and only do His good will?
If we do not justify what we live and preach, then we condemn our own living and preaching.
We cannot preach it is impossible not to continue sinning on earth, and not justify it as
inevitable in this life.
Inevitable sinning is preaching for the unrepented sinners to be justified in it.
I reject any bad news preaching, that declares it impossible to walk as Jesus walked, nor always please God '100% of the time'...
Many applaud that as good news preaching, because it justifies not always pleasing the Father. We see them clapping each other on the back for being so 'boldly' honest and humble.
For the people you describe , of which I have never known one personally the one biblical application that immediately comes to mind is that " God is not mocked"
It is true, that some do brag about their continued 'already forgiven' sinning. I have met them.
However, the Scripture is not about open mockers of God's judgment, but about preaching a mockery of His judgment of works. Specifically about how He does not condemn the evil works of His own people, but only of those not naming His name:
Gal 6:6
Let him that is taught in the word communicate unto him that teacheth in all good things.
Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.
Rom 2:3
And thinkest thou this, O man, that judgest them which do such things, and doest the same, that thou shalt escape the judgment of God? Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth thee to repentance?
Once again, it's the very few who come out and say such things openly, but it's them that preach such things making a mockery of God's judgment, as being
with respect of persons.
Some Jews did so by having the law in writing, though not doing the law, and some Christians do so by having faith alone, though not doing the word.
They each cause the law and grace of Christ to be blasphemed, by preaching they are uncondemned in their own trsngressions, as opposed to other condemned transgressors.
It's the grevious hypocrisy Paul is accuse of, by calling him the chiefest of transgressors, while in his gospel preaching the most to condemn the transgressions of others.
