Here is where the deception lies, and only because of not reconciling other scriptures together. As Jesus once said, "...a good tree can not produce bad fruit...." The proof that this is true today is found in this scripture...
1John 3:9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
We can not take this scripture as a means of saying a born again Christian can never sin, because any living being who is born of God knows that he still sins, but not on purpose.
You just said the scripture you sited was a lie.
As the Apostle Paul said....
Rom 7:16 Now if I do what I do not want, I agree with the law, that it is good.
Rom 7:17 So now it is no longer I who do it, but sin that dwells within me.
As long as we are still living in a physical body, sin will be present. Sin dwells in the flesh, not in man's born again spirit. Then why do Christians still sin?
Christians don't "still sin".
The first few verses of Ro 7 clearly show that it is speaking of a former time. Verse 5..."For when we WERE in the flesh..."
The entire middle of Ro 7 is about Paul's former life as a Pharisee; trying to live the Mosaic Law, but failing. And again, a reference to the past in verse 18; (that is, in my flesh).
And the end, especially verse 23; "But I see another law in my members, warring against the law of my mind, and bringing me into captivity to
THE LAW OF SIN which is in my members."...points again to a former time. Because....
we read in Romans 8:2...."For the law of the Spirit of life in Christ Jesus hath made me
FREE FROM THE LAW OF SIN and death.
Why would Paul be subject to something he is free of?
If you could see the truth of Ro 7, and its proximity to Ro 6, which speaks of baptism and the death of the flesh, you would see that Paul is making the past-present transition, and Ro 8 continues on into the life walked in the Spirit.
Rom 6:12 Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
Rom 6:13 Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God.
Who is responsible to keeping, and not letting sin reign in our mortal bodies? We are!!
Paul tells Timothy who the Lord uses for his work....
2Ti 2:19 Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.
Iniquity is lawlessness which is sin
2Ti 2:20 But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour.
2Ti 2:21 If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master's use, and prepared unto every good work.
Only a Christian who has "purged himself from iniquity (sin)" who will be used by God, prepared, and ready for every good work.
This second part of your post seems like a different man wrote it
The first part of your post makes a defense of sin, while the second exhorts us to righteousness.
There two minds can't coexist.
Choose which you will be a servant of.
