The perfection journey is a life-long pursuit and will only be completed through Yah’s favor and promises. The Apostle Paul, 25 years after he was converted, still was struggling with his human nature.
Romans 7:14-25 – 14 For we know that the law is spiritual: but I am carnal, sold under sin.
15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
16 If then I do that which I would not, I consent unto the law that it is good.
17 Now then it is no more I that do it, but sin that dwelleth in me.
18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
19 For the good that I would I do not: but the evil which I would not, that I do.
20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
21 I find then a law, that, when I would do good, evil is present with me.
22 For I delight in the law of Elohim after the inward man:
23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
24 O wretched man that I am! who shall deliver me from the body of this death?
25 I thank EL through Yahshua Messiah our Adonai. So then with the mind I myself serve the law of Elohim; but with the flesh the law of sin.
Paul knew that even as mature as he was or any of us will become, it is YHWH that will complete the process and keep His promises.
Philippians 3:12-15 – Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also, I am apprehended of Messiah Yahshua.
13 Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,
14 I press toward the mark for the prize of the high calling of Elohim in Messiah Yahshua.
15 Let us therefore, as many as be perfect, be thus minded: and if in anything ye be otherwise minded, Elohim shall reveal even this unto you.
