I like to use the biblical term "flesh" but I think we can all agree that sin still has a place in our mortal bodies? I believe this is what is called the "old man" "body of sin"
Old and New man. I just dont see how anyone could see these scriptures, any other way?
Paul is very carful to say "I know nothing good lives in MY FLESH" he is not saying we do not have anything good in us but in the flesh.
He did not say I know nothing good lives in my sinful nature.
We are also told we have a divine nature. So I do not use the term "sinful nature" but I understand that others feel this best describes the old fallen nature of the flesh.
psalms 51:1 (To the chief Musician, A Psalm of David, when Nathan the prophet came unto him, after he had gone in to Bathsheba.) Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.
2 Wash me throughly from mine iniquity, and cleanse me from my sin.
3 For I acknowledge my transgressions: and my sin is ever before me.
4 Against thee, thee only, have I sinned, and done this evil in thy sight: that thou mightest be justified when thou speakest, and be clear when thou judgest.
5 Behold, I was shapen in iniquity; and in sin did my mother conceive me.
6 Behold, thou desirest truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.
7 Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow.
8 Make me to hear joy and gladness; that the bones which thou hast broken may rejoice.
9 Hide thy face from my sins, and blot out all mine iniquities.
10 Create in me a clean heart, O God; and renew a right spirit within me.
11 Cast me not away from thy presence; and {take not thy holy spirit from me.} he is not going to remove his spirit from us that is what keeps us in check.one of the many functions of the Holy Spirit.. we do sin john wrote my little children i write to you that you sin not..but if you do you have a advocate
