So apparently Paul didn't know what he was writing about when he wrote, " "But now it is no longer me doing it, but sin that lives in me. For I know that nothing good lives in me, that is, in my flesh. For I want to do the good, but I cannot do it. For I do not do the good I want, but I do the very evil I do not want! Now if I do what I do not want, it is no longer me doing it but sin that lives in me."I disagree with the first part of that.
Men are servants of whom they serve. (Rom 6:16)
That part of Rom 7 described Paul's preconversion life while trying to satisfy God by obeying the Law.
All sin is willful. (James 1:14-15)
Should I believe you or the great apostle? Unsaved people are incapable of defeating their sin nature. That is why there is a need for a Savior.
Why do you not believe that every person inherited Adam's sin nature?
It is really odd that you cited James 1:14-15. Here are those verses, "But one is tempted by one’s own desire, being lured and enticed by it; then, when desire has conceived, it engenders sin, and sin, when it is fully grown, gives birth to death." How is being "lured and enticed" the same as "willful"?
