When we finally come to the truth,after all the kicking and screaming to ignore the truth,because we loved the flesh and it's ways,we can no longer sin because to be in the truth is to be led of the Spirit,in which a Spirit led life will not sin,so we are not sinners anymore at the point of receiving the truth,for we do not sin.
We are not sinners at the point of receiving the truth,for we do not sin,but we are still sinners from the past but were saved to not sin,but we are still sinners but the sin resides in the flesh,so like Paul said when he did good,evil was still with him,so with the flesh he serves sin,because the flesh is still sinful and does not change,but Paul ignored the temptations of the flesh,but with the mind he served Christ.
The flesh nature never changes when saved,but we ignore the temptations of the flesh,and with the mind we serve Christ.The sin nature is still with us when saved,which resides in the flesh,but we no longer go with the flesh,but with the Spirit.We are still sinners,because our flesh is attached to us,but we ignore the flesh,and are not sinners by being led of the truth by the Holy Spirit.
If people say they are led of the Spirit and it is believable,the best I have seen is they fall in and out of truth,for it seems like once and a while a fleshy thing will come out,and I say what,but I have seen some people for the most part really act a lot like Christ but a fleshy thing will appear once and a while,and I say what.
It happens with me,the little things,nothing serious,but it is still sin,but for the most part I abstain,and after Peter was converted he still held prejudism for 14 years against Gentiles,and Paul withstood him to the face about it,so it might happen once in a while,which is no excuse for it should not happen at all.
