Thank you for your elaboration Solo, I see where you are coming from but I must take note of a few more things (please bear with me an I seek to expound good doctrine):
Wait a minute. The evil flesh is not cleansed at all, it is still corrupted daily. I hope you are not confusing our sin nature (the flesh) with our physical body (having flesh). It seemed like you were doing that, correct me if I am wrong. But the physical body is neutral and can be used to glorify God. But the evil flesh (our old man) was crucified, yet it is still living (in a corrupt state) and Paul tells us to put off the old man (because it still lingers - and we have a choice, thats why there are warnings) and to put on the new.
Consider this quote from
this web site:
"
The Apostle Paul, whose marvelous regeneration has seldom if ever been surpassed by any, was compelled to say many, years after he had been regenerated that "I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me" (Rom. 7:18).
The flesh is in no way changed in regeneration; there will be a change wrought in the outward behavior of those who have been genuinely regenerated, but this is to be accounted for by the fact that the natural sinfulness of the flesh is restrained by the higher, spiritual nature of man which is changed in the new birth. It is because the fleshly nature is unchanged that there is the constant warfare between the two natures in the believer, to which reference is made in Galatians 5:16-17: "This I say then, Walk in the Spirit, and ye shall not fulfill the lust of the flesh. For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would."
I completely agree.
