No.
Unfettered: unrestrained, uninhibited.
Romans 7
15 I do not understand what I do. For what I want to do I do not do, but what I hate I do.16 And if I do what I do not want to do, I agree that the law is good.17 As it is, it is no longer I myself who do it, but it is sin living in me. 18 For I know that good itself does not dwell in me, that is, in my sinful nature. For I have the desire to do what is good, but I cannot carry it out. 19 For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing.20 Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.
The will of man is controlled by the flesh, whether he be a believer or not he still contends with the fleshly nature, the flesh’s will.
Anyone who states otherwise has an agenda, likely a false doctrine or even a false profession that he’s protecting.
