Paul would disagree
1What shall we say, then? Shall we go on sinning so that grace may increase? 2By no means! We died to sin; how can we live in it any longer? 3Or don't you know that all of us who were baptized into Christ Jesus were baptized into his death? 4We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life. - Romans 6
1In the same way, count yourselves dead to sin but alive to God in Christ Jesus. 12Therefore do not let sin reign in your mortal body so that you obey its evil desires. 13Do not offer the parts of your body to sin, as instruments of wickedness, but rather offer yourselves to God, as those who have been brought from death to life; and offer the parts of your body to him as instruments of righteousness. 14For sin shall not be your master, because you are not under law, but under grace. - Romans 6
Struggling with sin is one thing, we all do. It doesn't mean its okay to sin though. There's no excuse for a Christian to actively remain in sin. The Bible actually does address the attitude that its okay to remain in sin, and its not something to take lightly.
26If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left, 27but only a fearful expectation of judgment and of raging fire that will consume the enemies of God. 28Anyone who rejected the law of Moses died without mercy on the testimony of two or three witnesses. 29How much more severely do you think a man deserves to be punished who has trampled the Son of God under foot, who has treated as an unholy thing the blood of the covenant that sanctified him, and who has insulted the Spirit of grace? 30For we know him who said, "It is mine to avenge; I will repay,"[
d] and again, "The Lord will judge his people."[
e] 31It is a dreadful thing to fall into the hands of the living God.
32Remember those earlier days after you had received the light, when you stood your ground in a great contest in the face of suffering. 33Sometimes you were publicly exposed to insult and persecution; at other times you stood side by side with those who were so treated. 34You sympathized with those in prison and joyfully accepted the confiscation of your property, because you knew that you yourselves had better and lasting possessions.
35So do not throw away your confidence; it will be richly rewarded. 36You need to persevere so that when you have done the will of God, you will receive what he has promised. 37For in just a very little while,
"He who is coming will come and will not delay.
38But my righteous one[
f] will live by faith.
And if he shrinks back,
I will not be pleased with him."[
g] 39But we are not of those who shrink back and are destroyed, but of those who believe and are saved. - Hebrews 10
so unless we want to be counted as the enemies of God and claim their just punishment, I would say its not a good idea to advocate sin as a good thing.
Certainly we cannot save ourselves, or cleanse ourselves of sin. Thats what Christ's job on the cross was. He freed us of that. Our responsibility as believers now is to submit to the sanctifying power of the Holy Spirit as He conforms us to the image of Christ. We need to be walking in holiness, not rebelling against it. Even turning from temptation is a testament, not of our own strength, but of God's working in us.
7Submit yourselves, then, to God. Resist the devil, and he will flee from you. 8Come near to God and he will come near to you. Wash your hands, you sinners, and purify your hearts, you double-minded. 9Grieve, mourn and wail. Change your laughter to mourning and your joy to gloom. 10Humble yourselves before the Lord, and he will lift you up. - James 4
14Therefore, since we have a great high priest who has gone through the heavens,[
e] Jesus the Son of God, let us hold firmly to the faith we profess. 15For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who has been tempted in every way, just as we areyet was without sin. 16Let us then approach the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need. - Hebrews 4
